- 1. Phys. Rev. B 70, 245204 (2004) , “Silicon vacancy annealing and DI luminescence in 6H-SiC”, M. V. B. Pinheiro, E. Rauls, U. Gerstmann, S. Greulich-Weber, H. Overhof, and J.-M. SpaethCombining electron paramagnetic resonance measurements with ab initio calculations, we identify the VCCSi(SiCCSi) complex as a second annealing product of the silicon vacancy via an analysis of resolved carbon hyperfine interactions and of...

- 2. Phys. Rev. B 69, 45207 (2004) , “Intrinsic defects in GaN. I. Ga sublattice defects observed by optical detection of electron paramagnetic resonance”, K. H. Chow, L. S. Vlasenko, P. Johannesen, C. Bozdog, G. D. Watkins, Akira Usui, Haruo Sunakawa, Chiaki Sasaoka, Masashi MizutaIrradiation of GaN by 2.5-MeV electrons in situ at 4.2 K produces a broad photoluminescence (PL) band centered at 0.95 eV. Optical detection of electron paramagnetic resonance (ODEPR) in the band reveals two very similar, but distinct, signals, L5 and L6, which we identify as interstitial... (Read more)
- 3. Phys. Rev. Lett. 92, 125504 (2004) , “Low Energy Electron Irradiation Induced Deep Level Defects in 6H–SiC: The Implication for the Microstructure of the Deep Levels E1/E2”, X. D. Chen, C. L. Yang, M. Gong, W. K. Ge, S. Fung, C. D. Beling, J. N. Wang, M. K. Lui, and C. C. LingN-type 6HSiC samples irradiated with electrons having energies of Ee = 0.2, 0.3, 0.5, and 1.7 were studied by deep level transient technique. No deep level was detected at below 0.2 MeV irradiation energy while for Ee0.3 MeV,... (Read more)
- 4. Phys. Rev. Lett. 91, 109601 (2003) , “Comment on "Identification of Lattice Vacancies on the Two Sublattices of SiC"”, J. W. SteedsA Comment on the Letter by A. A. Rempel et al., Phys. Rev. Lett. 89, 185501 (2002). The authors of the Letter offer a Reply.... (Read more)
- 5. Phys. Rev. B 55, 2863 (1997) , “Optically detected magnetic resonance studies of defects in electron-irradiated 3C SiC layers”, N. T. Son, E. Sörman, W. M. Chen, C. Hallin, O. Kordina, B. Monemar, and E. JanzénDefects in electron-irradiated 3C SiC were studied by optically detected magnetic resonance (ODMR). In addition to the isotropic L2 center previously reported, an ODMR spectrum labeled L3, with a trigonal symmetry and an effective electron spin S=1, was observed after annealing at ?750 °C. The g...

- 6. J. Appl. Phys. 77, 837 (1995) , “Photoluminescence of radiation induced defects in 3C-SiC epitaxially grown on Si”, Hisayoshi Itoh, Masahito Yoshikawa, Isamu Nashiyama, Hajime Okumura, Shunji Misawa, Sadafumi YoshidaPhotoluminescence (PL) has been used to study defects introduced by 1-MeV-electron irradiation in cubic silicon carbide (3C-SiC) films epitaxially grown on Si substrates by means of chemical vapor deposition. A dominant PL line of 1.913 eV observed in 3C-SiC irradiated with electrons was found to... (Read more)
