EPR and theoretical studies of positively charged carbon vacancy in 4H-SiC

Umeda, T.Research Center for Knowledge Communities, University of Tsukuba, Tsukuba, Japan (author)

The carbon vacancy is a dominant defect in 4H-SiC, and the "E15" electron-paramagnetic-resonance (EPR) spectrum originates from positively charged carbon vacancies (VC+) at quasicubic sites. The observed state for EI5, however, has been attributed to a motional-averaged state with the C3v symmetry, and its true atomic structure has not been revealed so far. We here report low temperature (
