Bulk and Surface Effects on the Polytype Stability in SiC Crystals

Abstract:

We investigated with ab initio calculations the 3C-, 6H-, 4H- and 2H-SiC polytypes. We discuss the geometry and the energetics of bulk and surface relaxed structures ((0001) Si face and the (000-1) C face surfaces). The polytype stability is discussed regarding the bulk and surface effects.
