摘要：
Annealing of vacancies produced by heavy proton irradiation of float-zone (Fz) and P-doped Czochralski-grown (Cz) silicon has been investigated by positron lifetime spectroscopy. In Fz-Si divacancies are retained after irradiation, and these defects are completely annealed out at 700-degrees-C. In Cz P-doped silicon, impurities are found to enhance both the amount of retained vacancies as well as the tendency for vacancy clustering. Two annealing stages appear at 100-degrees-C and close to 450-degrees-C which seem to be a result of interstitial migration. Vacancy migration takes place in a wide temperature range between 100 and 1000-degrees-C.
