- 1. 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)
- 2. 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)
- 3. Phys. Rev. Lett. 93, 255502 (2004) , “Formation of Thermal Vacancies in Highly As and P Doped Si”, V. Ranki and K. SaarinenUsing positron annihilation measurements we observed the formation of thermal vacancies in highly As and P doped Si. The vacancies start to form at temperatures as low as 650 K and are mainly undecorated at high temperatures. Upon cooling the vacancies form stable vacancy-impurity complexes such as... (Read more)
