Nobel prize 2010 winners in physics are announced...
Nobel Prize 2010 winners in physics are announced and it's about nanoelectronics which happens to be my area of interest. The winners, two Russian-European (wait a second, Russia is in Europe right? Kidding. One is russian-dutch, the other is russian-british) physicists, are awarded with Nobel Prize for their contribution to the graphene research. But what is graphene? It's not in dictionaries yet, I suppose, as my spell checker keeps underlying graphene (again!) when I finish typing the word. Graphene is a planar structure composing of only carbon atoms bounded with conjugated pi-Bonds (sp2 hybrid bonds). In other words, its a single layer of graphite (what we use in pencils), which is actually nothing but an ordered structure of graphene layers on top of each other attracted by van der Waals Bonds. The single layer graphite -- graphene has fascinating electrical properties such as very high mobility and 2 dimensional charge carrier profile (2-DEG), allowing new device concepts which might be very useful in the future. We are definitely going to see some exotic devices using graphene in our every day life. I mean not like super coffee machines and flying cars but maybe energy efficient faster switching transistors. It's a deserved win.
