Research Abstract

Graphene, a monatomic sheet of carbon atoms, has attracted exclusive attention and got a Nobel prize in Physics in 2010. Since it is an ideal two dimensional sheet with quasi-particle which behaves as massless Dirac fermion with relativistic character, it is a notable material for both future electronics devices and fundamental physics. In this study, I measured and clarified the interesting nature of Dirac fermion by using a microscope with atomic resolution.
