Preliminary results of an attempt to acquire general knowledge about the behavior of defects in various polytypes of SiC, by means of theoretical methods, are presented. Ab initio LCGTO-LDA calculations in a molecular cluster model of the cubic crystal have been carried out on oxygen and nitrogen defects. Results of these, as well as those of plane wave LDA supercell calculations on structural defects in the literature are used to calibrate and reparametrize a quantum molecular dynamics method with density functional based tight binding Hamiltonian and a quasi-static semiempirical quantum chemical method, respectively.
