Nanowires grown on graphene have surprising structure

Apr. 23, 2013 ? When a team of University of Illinois engineers set out to grow nanowires of a compound semiconductor on top of a sheet of graphene, they did not expect to discover a new paradigm of epitaxy.

The self-assembled wires have a core of one composition and an outer layer of another, a desired trait for many advanced electronics applications. Led by professor Xiuling Li, in collaboration with professors Eric Pop and Joseph Lyding, all professors of electrical and computer engineering, the team published its findings in the journal Nano Letters.

Nanowires, tiny strings of semiconductor material, have great potential for applications in transistors, solar cells, lasers, sensors and more.

"Nanowires are really the major building blocks of future nano-devices," said postdoctoral researcher Parsian Mohseni, first author of the study. "Nanowires are components that can be used, based on what material you grow them out of, for any functional electronics application."

Li's group uses a method called van der Waals epitaxy to grow nanowires from the bottom up on a flat substrate of semiconductor materials, such as silicon. The nanowires are made of a class of materials called III-V (three-five), compound semiconductors that hold particular promise for applications involving light, such as solar cells or lasers.

The group previously reported growing III-V nanowires on silicon. While silicon is the most widely used material in devices, it has a number of shortcomings. Now, the group has grown nanowires of the material indium gallium arsenide (InGaAs) on a sheet of graphene, a 1-atom-thick sheet of carbon with exceptional physical and conductive properties.

Thanks to its thinness, graphene is flexible, while silicon is rigid and brittle. It also conducts like a metal, allowing for direct electrical contact to the nanowires. Furthermore, it is inexpensive, flaked off from a block of graphite or grown from carbon gases.

"One of the reasons we want to grow on graphene is to stay away from thick and expensive substrates," Mohseni said. "About 80 percent of the manufacturing cost of a conventional solar cell comes from the substrate itself. We've done away with that by just using graphene. Not only are there inherent cost benefits, we're also introducing functionality that a typical substrate doesn't have."

The researchers pump gases containing gallium, indium and arsenic into a chamber with a graphene sheet. The nanowires self-assemble, growing by themselves into a dense carpet of vertical wires across the surface of the graphene. Other groups have grown nanowires on graphene with compound semiconductors that only have two elements, but by using three elements, the Illinois group made a unique finding: The InGaAs wires grown on graphene spontaneously segregate into an indium arsenide (InAs) core with an InGaAs shell around the outside of the wire.

"This is unexpected," Li said. "A lot of devices require a core-shell architecture. Normally you grow the core in one growth condition and change conditions to grow the shell on the outside. This is spontaneous, done in one step. The other good thing is that since it's a spontaneous segregation, it produces a perfect interface."

So what causes this spontaneous core-shell structure? By coincidence, the distance between atoms in a crystal of InAs is nearly the same as the distance between whole numbers of carbon atoms in a sheet of graphene. So, when the gases are piped into the chamber and the material begins to crystallize, InAs settles into place on the graphene, a near-perfect fit, while the gallium compound settles on the outside of the wires. This was unexpected, because normally, with van der Waals epitaxy, the respective crystal structures of the material and the substrate are not supposed to matter.

"We didn't expect it, but once we saw it, it made sense," Mohseni said.

In addition, by tuning the ratio of gallium to indium in the semiconductor cocktail, the researchers can tune the optical and conductive properties of the nanowires.

Next, Li's group plans to make solar cells and other optoelectronic devices with their graphene-grown nanowires. Thanks to both the wires' ternary composition and graphene's flexibility and conductivity, Li hopes to integrate the wires in a broad spectrum of applications.

"We basically discovered a new phenomenon that confirms that registry does count in van der Waals epitaxy," Li said.

This work was supported in part by the Department of Energy and the National Science Foundation. Postdoctoral researcher Ashkan Behnam and graduate students Joshua Wood and Christopher English also were co-authors of the paper. Li also is affiliated with the Beckman Institute for Advanced Science and Technology, the Micro and Nanotechnology Lab, and the Frederick Seitz Materials Research Lab, all at the U. of I.

Huawei tones down long-term expansion target for enterprise sales

By Yimou Lee and Lee Chyen Yee

HONG KONG (Reuters) - Huawei Technologies Co Ltd, the world's No.2 telecoms equipment maker, toned down its long-term target for networking equipment sales to enterprises, saying a prior figure was too optimistic.

Eric Xu, Huawei executive vice president and one of its rotating CEOs, also voiced frustration with security issues that are thwarting the Chinese company in the key U.S. telecoms equipment market.

Xu said the company's enterprise unit, targeted for expansion as sales to telecoms operators turned sluggish, was aiming to boost sales to $10 billion by 2017, below a goal by Huawei executives last year of $15 billion. The division posted 11.5 billion yuan ($1.9 billion) in sales last year.

"If we can achieve $10 billion sales by 2017, that will be good enough for me," Xu told an analyst conference in Shenzhen, China, where the company is headquartered.

He said $10 billion was a more realistic target after assessing the market situation more closely.

"We now have a deeper understanding of the market," he said.

Huawei's enterprise unit, which contributed around 5 percent to total revenues in 2012, sells network gear to companies and corporations.

Its flagship carrier business, which accounted for nearly three quarters of its revenue, sells equipment to telecom operators.

Its consumer group sells handsets and tablets to end-users and has been rising in the ranks of the booming smartphone market to compete with high-profile brands such as Apple Inc and Samsung Electronics Co Ltd.

Xu also said on Tuesday that the company expects its IT business, which provides IT-related gear and services to enterprises and telecoms operators, to generate between $800 million and $1 billion in revenue this year.

The Chinese firm, founded by former Chinese military officer Ren Zhengfei in 1987, faces obstacles in the telecoms equipment business in the United States, Canada and Australia due to security concerns. Huawei is not allowed to sell telecoms equipment to U.S. carriers.

Last year, the U.S. House Intelligence Committee released a report urging U.S. telecommunications companies not to do business with Huawei and ZTE Corp, another Chinese equipment maker.

It said potential Chinese state influence on the companies posed a threat to U.S. security. Those concerns have benefited global rivals such as Ericsson, Alcatel-Lucent SA and Nokia Siemens Networks.

Xu replied with exasperation on Tuesday when asked about U.S. congressional committee hearings on Huawei and ZTE.

"We are not interested in the U.S. market anymore. Generally speaking, it's not a market that we pay much attention to." He did not respond to a follow-up question about the company's continuing business selling mobile handsets in the United States.

ISTANBUL (AP) ? U.S. Secretary of State John Kerry on Sunday urged Turkey to speed up and cement an American-brokered rapprochement with Israel, and he explored with Palestinian officials new ways to relaunch Mideast peace efforts.

Kerry tried to advance those second-term foreign policy priorities for President Barack Obama in meetings with Turkey's foreign minister, Ahmet Davutoglu, and the Palestinian Authority president, Mahmoud Abbas.

Kerry also said he had made it clear to the Turks that a planned trip to the Hamas-controlled Gaza Strip by Prime Minister Recep Tayyip Erdogan after his May 16 visit to the White House "would be better delayed and that it shouldn't take place at this point in time.

Both Israel and Abbas, whose Palestinian Authority is based in the West Bank, oppose the Gaza visit.

"We would like to see the parties begin with as little outside distraction as possible. So our sense is that it would be more helpful to wait for the right circumstances," said Kerry, who did not meet with Erdogan on this stop in Turkey.

On a trip to Israel last month, Obama secured a pledge from Turkish and Israeli leaders to normalize ties that broke down after a 2010 Israeli raid on a Gaza-bound aid flotilla that killed eight Turks and a Turkish-American.

But the rapprochement has been slow, fueling concerns that Turkey may be backsliding on its commitment.

Israeli and Turkish negotiators plan to meet this coming week to discuss Turkey's demand for compensation for victims of the flotilla.

U.S. officials hope the discussions will jumpstart the process of restoring full diplomatic relations and exchanging ambassadors between two countries that Washington sees as vital strategic partners in the volatile Middle East.

The raid sparked throughout outrage in Muslim-majority Turkey, making it politically difficult for Erdogan to bend to persistent U.S. appeals to improve relations with Israel.

In March, Obama extracted an apology for the raid from Israeli Prime Minister Benjamin Netanyahu that broke the stalemate.

Kerry said he understood the anger and frustration of those Turks who lost friends and family in the raid. The former Massachusetts senator said last week's Boston Marathon bombings made him acutely aware of the emotions involved.

"It affects the community, it affects the country. But going forward, you know, we have to find the best way to bring people together and undo these tensions and undo these stereotypes and try to make peace," he said.

Kerry said he had a "prolonged and constructive" discussion with Davutoglu, about "the importance of completing the task with respect to the renewal of relations between Turkey and Israel."

Kerry added that he believed Erdogan and Davutoglu "are deeply committed to fulfilling all of the obligations of that understanding."

U.S. officials are keen to see substantive process by the time Erdogan comes to Washington.

"We would like to see us get to a point where we are moving on improving the situation in Gaza, which was part of the agreement ... and where we are also completing the tasks of moving to full diplomatic relations between the countries, which would be very beneficial to everyone," he said.

With Abbas, Kerry discussed ways to improve the Palestinians' living conditions as a confidence-building measure to improve the atmosphere for a resumption of peace talks with Israel.

Kerry has said he fears there is only a two- or three-year window of opportunity to reach a deal on a two-state solution that would end the decades-old Israeli-Palestinian conflict and wants to move as quickly as possible.

Kerry was in Istanbul primarily to attend an international conference on Syria that began on Saturday and stretched into early Sunday as participants debated how best to boost aid to rebels trying to topple Syrian President Bashar Assad's government.

He announced that the Obama administration would double its nonlethal assistance to the Syrian opposition with an additional $123 million in supplies that could include for the first time armored vehicles, body armor, night vision goggles and other defensive military supplies.

"I can't tell you how quickly it will change things on the ground," Kerry said Sunday. "I can promise you that as soon as I return to Washington, I am going to press as hard as I can" to get it to the opposition within a matter of weeks.

"This has to happen quickly, it has to have an impact," he added.

The additional aid, which brings total nonlethal U.S. assistance to the opposition to $250 million since the fighting began more than two years ago, "underscores the United States' firm support for a political solution to the crisis in Syria and for the opposition's advancement of an inclusive, tolerant vision for a post-Assad Syria," Kerry said.

The U.S. pledge was the only tangible, public offer of new international support at the meeting of the foreign ministers of the 11 main countries supporting the opposition and fell well short of what the opposition has been appealing for: weapons and direct military intervention to stop the violence that has killed more than 70,000 people.

The Syrian National Coalition is seeking drone strikes on sites from which the regime has fired missiles, the imposition of no-fly zones and protected humanitarian corridors to ensure the safety of civilians.

With the exception of the United States, none of the participants offered new assistance, although European nations are considering changes to an arms embargo that would allow weapons transfers to the Syrian opposition.

Kerry ended the day in Brussels, where he plans talks with European officials and was to meet Russian Foreign Minister Sergey Lavrov on the sidelines of a NATO-Russia Council meeting. He has said he has not given up on persuading Moscow to reverse its support for Assad.

Indian police arrest suspect for rape of 5-year-old as anger builds

NEW DELHI (Reuters) - Indian police arrested a man on allegations of rape and torture of a five-year-old girl in New Delhi, a spokesman said on Saturday, after the incident triggered protests and revived memories of a brutal December assault on a woman that shook the country.

The man, 22, was arrested from eastern Bihar state, and is being brought to the capital, Police spokesman Rajan Bhagat said. The accused was a neighbor of the girl and did odd jobs, he said.

The assault on the girl, which left her in a critical condition, revived memories of the gang rape by five adult men and a teenaged boy of a 23-year-old physiotherapy student on a bus on December 16 in New Delhi.

That woman died of her injuries in a Singapore hospital where she was brought as anger poured in the streets of Delhi and elsewhere over the lack of safety for women.

Television images on Saturday showed people again gathered in front of the Delhi police headquarters and the specialty hospital where the latest victim was battling for life, chanting slogans and demanding better law enforcement in a city of 16 million people.

More protests were planned for Saturday, and security has been beefed up, television reports said.

The girl, whose parents work as laborers and live in a slum in the outskirts of Delhi, went missing from home on April 15, according to Manish Sisodia, an official of the Aam Aadmi Party which organized Friday's protest.

She was found with bruise marks on her body in the suspect's house in a semi-conscious condition on Thursday by police after her parents had registered a complaint, media reports said.

The suspect allegedly held the girl hostage for three days during which he raped and tortured her.

B.N. Bansal, a doctor from the Swami Dayanand Hospital, said that the young victim had undergone an operation after she was brought in. "The next 48 hours will be crucial for her."

Prime Minister Manmohan Singh's office said in a statement that he was deeply disturbed by the latest incident. In December his administration had faced criticism for failing to respond to public anger over the horrific attack on the physiotherapy student.

The unprecedented protests by thousands of people across India eventually forced Singh's government to pass tougher laws to fight gender crimes in March.

But activists on Friday said the laws were not enough to deter sex offenders in India's largely patriarchal societies.

"If you thought just bringing in a new law will stop crimes, your are wrong. They will reduce, but won't stop. You need community policing to stop these crimes," activist Kiran Bedi told an Indian TV channel.
