- 1. Phys. Rev. B 75, 195335 (2007) , “Computational and experimental imaging of Mn defects on GaAs (110) cross-sectional surfaces”, A. Stroppa, X. Duan, M. Peressi, D. Furlanetto, and S. ModestiWe present a combined experimental and computational study of the (110) cross-sectional surface of Mn δ-doped GaAs samples. We focus our study on three different selected Mn defect configurations not previously studied in detail, namely surface interstitial Mn, isolated and in pairs, and... (Read more)
- 2. Phys. Rev. B 75, 045210 (2007) , “Positron trapping kinetics in thermally generated vacancy donor complexes in highly As-doped silicon”, K. Kuitunen, K. Saarinen, and F. TuomistoWe have measured positron lifetime and Doppler broadening in highly As-doped silicon containing thermally generated V-As3 defect complexes (vacancy is surrounded by three arsenic atoms). We observe positron detrapping from the V-As3 defect complex and determine... (Read more)
- 3. Phys. Rev. Lett. 98, 265502 (2007) , “Monovacancy and Interstitial Migration in Ion-Implanted Silicon”, P. G. Coleman and C. P. BurrowsThe migration of monovacancies (V0) and self-interstitials (I) has been observed in ion-implanted low-doped float-zone silicon by variable-energy positron annihilation spectroscopy. V0 and I were created by the in situ implantation of ~20 keV... (Read more)
- 4. Phys. Rev. B 74, 195202 (2006) , “Interstitial-mediated mechanisms of As and P diffusion in Si: Gradient-corrected density-functional calculations”, Scott A. Harrison, Thomas F. Edgar, and Gyeong S. HwangGradient-corrected density-functional calculations are used to determine the structure, stability, and diffusion of arsenic-interstitial and phosphorus-interstitial pairs in the positive, neutral, and negative charge states. For both cases, our calculations show that the neutral pair will be... (Read more)
- 5. Appl. Phys. Lett. 87, 231905 (2005) , “Structure, stability, and diffusion of arsenic-silicon interstitial pairs”, Scott A. Harrison, Thomas F. Edgar, and Gyeong S. HwangRecent experimental studies [A. Ural, P. B. Griffin, and J. D. Plummer, J. Appl. Phys. 85, 6440 (1999); R. Kim, T. Hirose, T. Shano, H. Tsuji, and K. Taniguchi, Jpn. J. Appl. Phys. 41, 227 (2002); S. Solmi, M. Ferri, M. Bersani, D. Giubertoni, and V. Soncini, J. Appl. Phys. 94,... (Read more)
- 6. 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)
- 7. Phys. Rev. 174, 881 (1968) , “Defects in Irradiated Silicon: Electron Paramagnetic Resonance and Electron-Nuclear Double Resonance of the Arsenic- and Antimony-Vacancy Pairs”, Edward L. Elkin and G. D. WatkinsTwo EPR spectra are observed in irradiated silicon (designated Si-G23 and Si-G24) which are identified with the neutral charge states of a lattice vacancy adjacent to a substitutional arsenic or antimony atom, respectively. EPR and ENDOR studies reveal a high degree of similarity between these... (Read more)
