A team led by Cory Dean, assistant professor of physics at Columbia University, and James Hone, Wang Fong-Jen Professor of Mechanical Engineering at Columbia Engineering, has definitively observed an ...
Effect of charged impurity correlation on transport in monolayer and bilayer graphene
charged impurity correlation transport monolayer bilayer graphene
2012/2/27
We study both monolayer and bilayer graphene transport properties taking into account the presence of correlations in the spatial distribution of charged impurities. In particular we find that the exp...
Chiral tunneling in single and bilayer graphene
Chiral tunneling single-layer bilayer graphene its semiclassical theory
2011/7/28
Abstract: We review chiral (Klein) tunneling in single-layer and bilayer graphene and present its semiclassical theory, including the Berry phase and the Maslov index. Peculiarities of the chiral tunn...

We investigate band-gap tuning of bilayer graphene between hexagonal boron nitride sheets,
by external electric elds. Using density functional theory, we show that the gap is continuously tunable fr...
We describe the gated bilayer graphene system when it is subjected to intense terahertz frequency electromagnetic radiation. We examine the electron band structure and density of states via exact diag...
