 Summary:

I am Hatef Sadeghi, graduate student in the field of Electronics Engineering (Nanoelectronics Devices) at University of Technology in Malaysia (UTM) and a member of Computational Nanoelectronics (CoNE) Research Group. My main research area is modeling and simulation of Nanoelectronics Devices specifically based on Graphene Nanoribbon and carbon Nanotube. I have done my master project entitled: "Carrier Statistics and Conductance Modeling of Bilayer Graphene Nonoribbon (BGN) in BGN Filed Effect Transistor under Datuk Prof Ishak supervision and Prof. Dr. Razali Co-Suppervison." I have done some researches on this area which the details are reflected in here. I was born in Mianeh, a small city in the state of Azerbaijan-e-Sharqi, IRAN and now I am living in Skudai, Malaysia.
  Thank you for visiting my academic web page.

Future Applications of Graphene

The 2010 Nobel prize for physics was awarded Tuesday to two professors from the University of Manchester in England for "groundbreaking" experiments with the two-dimensional material graphene.
The professors are Andre Geim and Konstantin Novoselov, both originally from Russia.
