摘要
We present a first-principles study of ionicity in SiC polytypes using two different approaches, a static and a dynamic one. Our calculations are performed within the framework of density-functional theory (DFT) and linear-response approach to DFT. Special attention is paid in applying these concepts to hexagonal polytypes and discussing the pressure-induced increase of the ionicity in SiC.
