- 1. Phys. Rev. Lett. 96, 145501 (2006) , “Identification of the Carbon Antisite-Vacancy Pair in 4H-SiC”, T. Umeda, N. T. Son, J. Isoya, E. Janzn, T. Ohshima, N. Morishita, H. Itoh, A. Gali, M. BockstedteThe metastability of vacancies was theoretically predicted for several compound semiconductors alongside their transformation into the antisite-vacancy pair counterpart; however, no experiment to date has unambiguously confirmed the existence of antisite-vacancy pairs. Using electron paramagnetic resonance and first principles calculations we identify the SI5 center as the carbon antisite-vacancy pair in the negative charge state (CSiVC-) in 4H-SiC. We suggest that this defect is a strong carrier-compensating center in n-type or high-purity semi-insulating SiC.

GorelkinskiiAn electron-paramagnetic resonance (EPR) study of proton-irradiated silicon has revealed two new EPR spectra labeled Si-AA13 and Si-AA14. Spectrum AA13 has C3v symmetry (g = 1.9985 and g = 2.0024 ± 0.0002), AA14 C1 symmetry. These spectra correspond to positive (B+) and negative (B−)... (Read more)

Gorelkinskii.A new metastable complex in monocrystalline silicon irradiated at with protons has been studied. Electron paramagnetic resonance (EPR) Si-AA13 ( symmetry) and Si-AA14 ( symmetry) spectra as well as the known Si-A18 spectrum originate from different molecular configurations of the complex. A...

Watkins.By combining several spectroscopic techniques, we have observed a new type of bistable center in electron-irradiated silicon and have identified it as an interstitial-carbon–substitutional-carbon pair. The positive and negative charge states of the defect share a common stable configuration which... (Read more)

Ascarelli.Magnesium diffused into silicon forms a deep-double-donor state. Depending on the compensation, the distinct valence states Mg0, Mg+, or Mg++ are possible. EPR measurements have been performed at 55 GHz on the paramagnetic valence state Mg+ at... (Read more)
