The Nobel Prize in Physics 2010 was awarded jointly to Andre Geim and Konstantin Novoselov "for groundbreaking experiments regarding the two-dimensional material graphene"

2004年做出來的東西,2010年就拿獎了,不可思議的快!!!!

前幾天大家還在實驗室說無論如何現在頒給Graphene 都太早了,沒想到不到一個禮拜瑞典人就吐我們槽…吐得好啊!至少實驗室接下來更不用愁funding了

諾貝爾物理獎 兩俄裔學者共享
2010-10-05 中國時報 【中央社】
瑞典皇家科學院今天宣布,俄羅斯出身的學者蓋姆(Andre Geim)與諾伏西羅夫(Konstantin Novoselov)今天共同獲得今年諾貝爾物理學獎,他們是研究石墨烯(graphene)的先驅,而這種薄膜號稱是21世紀的神奇材料。

這兩位學者都在俄國展開學術生涯,但如今任職英國的曼徹斯特大學。蓋姆擁有荷蘭國籍,諾伏西羅夫則擁有俄國與英國雙重國籍。

瑞典皇家科學院讚揚石墨烯是「完美的原子晶格」,因為這種材料在電腦、家用裝置和運輸方面都有很大發展潛力。

皇家科學院讚許51歲的蓋姆和36歲的諾伏西羅夫說,他們「證明了碳以如此平面形式呈現時,擁有卓越的特性,這種特性源自量子物理學的奇異世界」。

他們研究上的突破導致石墨烯的發現,這種形式的碳獲推崇將成為下個世代的超級材料。

石墨烯的厚度只有一個原子,是世界最薄卻也是最堅強的奈米材料,幾乎透明,而且能夠導電和傳熱。因此,石墨烯獲看好是可能取代矽半導體的材料。

石墨烯製作的電晶體在理論上可以超越如今使用的典型電腦晶片,傳輸速度更快,而且更耐高溫。這將可解決晶片工程師面對的越來越大問題,就是他們既希望增強功效,又希望縮小它的尺寸,而且不會提升溫度,這是電腦運算上的一大難題。

而石墨烯透明的特性則意味它可能用於觸控螢幕,甚至是太陽能電池,而且與塑膠混合使用時,可提供輕而超強的合成材料,供下一代衛星、飛機和汽車使用。(譯者:中央社林治平)991005


Press Release
5 October 2010

The Royal Swedish Academy of Sciences has decided to award the Nobel Prize in Physics for 2010 to

Andre Geim
University of Manchester, UK

and

Konstantin Novoselov
University of Manchester, UK

"for groundbreaking experiments regarding the two-dimensional material graphene"


Graphene – the perfect atomic lattice
A thin flake of ordinary carbon, just one atom thick, lies behind this year’s Nobel Prize in Physics. Andre Geim and Konstantin Novoselov have shown that carbon in such a flat form has exceptional properties that originate from the remarkable world of quantum physics.

Graphene is a form of carbon. As a material it is completely new – not only the thinnest ever but also the strongest. As a conductor of electricity it performs as well as copper. As a conductor of heat it outperforms all other known materials. It is almost completely transparent, yet so dense that not even helium, the smallest gas atom, can pass through it. Carbon, the basis of all known life on earth, has surprised us once again.

Geim and Novoselov extracted the graphene from a piece of graphite such as is found in ordinary pencils. Using regular adhesive tape they managed to obtain a flake of carbon with a thickness of just one atom. This at a time when many believed it was impossible for such thin crystalline materials to be stable.

However, with graphene, physicists can now study a new class of two-dimensional materials with unique properties. Graphene makes experiments possible that give new twists to the phenomena in quantum physics. Also a vast variety of practical applications now appear possible including the creation of new materials and the manufacture of innovative electronics. Graphene transistors are predicted to be substantially faster than today’s silicon transistors and result in more efficient computers.

Since it is practically transparent and a good conductor, graphene is suitable for producing transparent touch screens, light panels, and maybe even solar cells.

When mixed into plastics, graphene can turn them into conductors of electricity while making them more heat resistant and mechanically robust. This resilience can be utilised in new super strong materials, which are also thin, elastic and lightweight. In the future, satellites, airplanes, and cars could be manufactured out of the new composite materials.

This year’s Laureates have been working together for a long time now. Konstantin Novoselov, 36, first worked with Andre Geim, 51, as a PhD-student in the Netherlands. He subsequently followed Geim to the United Kingdom. Both of them originally studied and began their careers as physicists in Russia. Now they are both professors at the University of Manchester.

Playfulness is one of their hallmarks, one always learns something in the process and, who knows, you may even hit the jackpot. Like now when they, with graphene, write themselves into the annals of science.
