DOI: 10.1103/physrevb.101.184108
Abstract: Combining electron paramagnetic resonance (EPR) spectroscopy and first-principles density functional theory calculations we have identified the carbon monovacancy center and a second carbon vacancy-related defect, the carbon vacancy--carbon antisite defect in $3C$-SiC. In close analogy… read more here.
