- 1. Phys. Rev. B 71, 193204 (2005) , “Angular correlation of annihilation radiation associated with vacancy defects in electron-irradiated 6H-SiC”, A. Kawasuso, T. Chiba, T. HiguchiElectron-positron momentum distributions associated with vacancy defects in 6H-SiC after irradiation with 2-MeV electrons and annealing at 1000 °C have been studied using angular correlation of annihilation radiation measurements. It was confirmed that the above vacancy defects have... (Read more)
- 2. Phys. Rev. Lett. 89, 185501 (2002) , “Identification of Lattice Vacancies on the Two Sublattices of SiC”, A. A. Rempel, W. Sprengel, K. Blaurock, K. J. Reichle, J. Major, and H.-E. SchaeferThe identification of atomic defects in solids is of pivotal interest for understanding atomistic processes and solid state properties. Here we report on the exemplary identification of vacancies on each of the two sublattices of SiC by making use of (i) electron irradiation, (ii) measurements of... (Read more)
- 3. Phys. Rev. B 62, 8016 (2000) , “Isochronal annealing studies of n-type 6H-SiC with positron lifetime spectroscopy”, C. C. Ling, C. D. Beling, S. Fungn-type 6H silicon carbide has been studied using positron lifetime spectroscopy with isochronal annealing temperatures of 400, 650, 900, 1200, and 1400 °C. In the as-grown sample, we have identified the VSi vacancy, the VCVSi divacancy, and probably the VC... (Read more)
- 4. Phys. Rev. B 51, 1928 (1995) , “Carbon and silicon vacancies in electron-irradiated 6H-SiC”, S. Dannefaer, D. Craigen, D. KerrPositron-lifetime and Doppler-broadening spectroscopies were used to investigate vacancies formed by 2.2- and 10-MeV electrons. Carbon vacancies yield a positron lifetime of 160 ps, only 15 ps longer than the bulk lifetime, and the Doppler-broadening S parameter is very close to that for the bulk.... (Read more)
