Abstract

The ionicity of SiC polytypes and its pressure dependence is investigated by employing ab initio calculations using density-functional theory within the local-density approximation. Two approaches are used to quantify ionicity: a static one introduced by Garcia and Cohen involving a decomposition of the valence-charge density into symmetric and antisymmetric contributions with respect to the bond ...
