- 1. Phys. Rev. Lett. 98, 206403 (2007) , “H-Induced Dangling Bonds in H–Isoelectronic-Impurity Complexes Formed in GaAs1-yNy Alloys”, A. Amore Bonapasta, F. Filippone, and G. MattioliComplexes formed by H and the isoelectronic impurity N in GaAs1-yNy alloys have been widely investigated because the significant effects of N on the GaAs properties and their passivation by H represent a unique tool for a defect engineering of semiconductors....

- 2. Phys. Rev. B 70, 235211 (2004) , “Structure and vibrational spectra of carbon clusters in SiC”, Alexander Mattausch, Michel Bockstedte, and Oleg PankratovThe electronic, structural, and vibrational properties of small carbon interstitial and antisite clusters are investigated by ab initio methods in 3C- and 4H-SiC. The defects possess sizable dissociation energies and may be formed via condensation of carbon interstitials, e.g.,... (Read more)
- 3. Phys. Rev. B 68, 205201 (2003) , “Ab initio study of the migration of intrinsic defects in 3C-SiC”, Michel Bockstedte, Alexander Mattausch, and Oleg PankratovThe diffusion of intrinsic defects in 3C-SiC is studied using an ab initio method based on density functional theory. The vacancies are shown to migrate on their own sublattice. The carbon split-interstitials and the two relevant silicon interstitials, namely the tetrahedrally... (Read more)
- 4. Phys. Rev. B 67, 205202 (2003) , “Formation and annealing of nitrogen-related complexes in SiC”, U. Gerstmann, E. Rauls, Th. Frauenheim, and H. OverhofWe propose a mechanism for the annealing of vacancy-related defects in SiC, based on ab initio total energy calculations. Our mechanism is based on the formation and migration of carbon and nitrogen split interstitials resulting in CSi(NC)n or... (Read more)
- 5. Phys. Rev. Lett. 87, 235501 (2001) , “Thermal Double Donors and Quantum Dots”, J. Coutinho, R. Jones, L. I. Murin, V. P. Markevich, J. L. Lindstr?m, S. ?berg, P. R. Briddon.Combined local mode spectroscopy and ab initio modeling are used to demonstrate for the first time that oxygen atoms in thermal double donors (TDD) in Si are in close proximity. The observed vibrational modes in 16O, 18O, and mixed isotopic samples are consistent with a model... (Read more)
- 6. Physica B 302-303, 212-219 (2001) , “Magnetic resonance studies of shallow donor centers in hydrogenated Cz–Si crystals”, B. Langhanki, S. Greulich-Weber, J. ?M. Staeth, V. P. Markevich, L. I. Murin, T. Mchedlidze, M. Suezawa.A complex magnetic resonance study (EPR, electrically detected EPR, ENDOR) of hydrogen-related radiation-induced shallow donors in silicon has been performed. Three species of this donor family (D1–D3) were observed earlier by means of infrared absorption measurements in hydrogenated... (Read more)
- 7. Mater. Sci. Eng. B 71, 263 (2000) , “Comparison of Electronic Structure and Properties of Hydrogen-Associated and Thermal Double Donors in Silicon”, S. Zh. Tokmoldin, B. N. Mukashev, Kh. A. Abdullin, Yu. V. Gorelkinskii and B. PajotInfrared (IR) and electron paramagnetic resonance (EPR) studies of quenching-dependent hydrogen-related double donor (HDD) formed in proton-implanted n-Si and p-Si upon annealing above 300°C were carried out. IR data taken at liquid He and N2 reveal that quenching-dependent IR absorption lines... (Read more)
- 8. Phys. Rev. B 47, 6363-6380 (1993) , “Electron paramagnetic resonance of multistable interstitial-carbonsubstitutional-group-V-atom pairs in silicon”, X. D. Zhan, G. D. WatkinsA total of five new electron paramagnetic resonance (EPR) centers are observed in electron-irradiated P-, As-, and Sb-doped silicon. Three are identified as arising from the neutral charge state of the stable configuration and two of the four metastable configurations of an... (Read more)
