Excitonic effects in bulk CuBr using Time Dependent DFT

Abstract

With a view towards studying the effect of lowering the dimensionality on excitons, we have first investigated the excitonic effects in bulk CuBr, which is a direct band-gap semiconductor with zinc blende structure. We have employed time-dependent density functional theory for this investigation. Both, the random phase approximation and the bootstrap… (More)
