摘要: The Raman $2D$ band---important for the analysis of graphene---shows a splitting uniaxial strain. depends on strength and direction applied strain polarization incident outgoing light. We expand double-resonance model in order to explain dependence splitting. this gives distinct insight into origin band. Our prediction agrees well with recent experiments.
