摘要
Recent results on ab initio calculations of electronic and structural properties of SiC surfaces are reviewed. Particular attention is given to cubic SiC surfaces, and to the (0 0 1) plane of the cubic polytype, which is still open to controversy from both the theoretical and experimental side. Furthermore, new exciting evidence of self-aggregating low-dimensional structures has been reported, which is well characterized by first-principles simulations. Results on both stoichiometric and non-stoichiometric surface reconstructions for the cubic and hexagonal polytypes are presented, as well as some recent calculations regarding adsorption and initial stages of nitride and oxide growth on crystalline SiC.
