Space dependent Fermi velocity in strained graphene [PDF]
Fernando de Juan, Mauricio Sturla, Maria A. H. VozmedianoWe resolve some apparent discrepancies between two different models for curved graphene: the one based on tight binding and elasticity theory, and the covariant approach based on quantum field theory in curved space. We demonstrate that strained or corrugated samples will have a space dependent Fermi velocity in either approach that can affect the interpretation of some experiments.View original: http://arxiv.org/abs/1201.2656
