- 1. Phys. Rev. B 75, 085208 (2007) , “Clustering of vacancy defects in high-purity semi-insulating SiC”, R. Aavikko, K. Saarinen, F. Tuomisto, B. Magnusson, N. T. Son, and E. JanzénPositron lifetime spectroscopy was used to study native vacancy defects in semi-insulating silicon carbide. The material is shown to contain (i) vacancy clusters consisting of four to five missing atoms and (ii) Si-vacancy-related negatively charged defects. The total open volume bound to the...

- 2. Phys. Rev. B 74, 174122 (2006) , “Lithium colloids and color center creation in electron-irradiated Li2NH observed by electron-spin resonance”, F. Beuneu, P. Vajda, Y. Nakamori, and S. OrimoWe have irradiated Li2NH powder with MeV electrons at room temperature and investigated the introduced defects with electron spin resonance. Conduction electron spin resonance indicates the presence of nanosize metallic Li colloids seen as a Lorentzian line with a g=2.0023 and a... (Read more)
- 3. Phys. Rev. B 74, 174120 (2006) , “Single-crystal silicon coimplanted by helium and hydrogen: Evolution of decorated vacancylike defects with thermal treatments”, C. Macchi, S. Mariazzi, G. P. Karwasz, R. S. Brusa, P. Folegati, S. Frabboni, and G. OttavianiSi p-type (100) samples were coimplanted at room temperature with He+ ions at 30 keV with a dose of 1×1016 ions/cm2 and successively with H+ ions at 24 keV with a dose of 1×1016 ions/cm2. A series of samples was... (Read more)
- 4. Phys. Rev. B 9, 4351-4361 (1974) , “EPR study of defects in neutron-irradiated silicon: Quenched-in alignment under <110>-uniaxial stress”, Young-Hoon Lee and James W. CorbettThe stress effect in an EPR study is first treated rigorously in terms of the piezospectroscopic tensor, taking account of the local symmetry of a defect. It is found that the degree of alignment (n?/n?) provides incisive information on the structure of a defect; in general, a... (Read more)
