Abstract

Only recently the well-resolved hyporfine structure of the P6/P7 EPR center has been experimentally observed. Based on the calculated hyperfine tensors we assign the P6/P7 center to the high spin state neutral divacancy, which is the ground state in agreement with the experiment. We propose a mechanism to explain the loss of divacancy signal at high temperature annealing in semi-insulating SiC samples. We discuss the possible correlation between the divacancy and some photoluminescence centers.
