Silicon Antisite in 4H SiC

Journal Article · · Physical Review Letters
Electron paramagnetic resonance spectrum with C{sub 3V} symmetry and a spin S=1/2 has been observed in p -type, electron-irradiated 4H SiC. Based on the observed {sup 29}Si hyperfine structures it is suggested that the defect is the isolated silicon antisite (Si{sub C}) . The spin S=1/2 and the observation of the defect only in p -type material suggest that the Si{sub C } is in the positive-charge state. A strong temperature dependence of the g value and hyperfine coupling constant of the Si{sub C }{sup +} center indicates a considerable lattice relaxation in the vicinity of the defect.
