摘要：

The temperature dependence of the irradiation-induced displacement of As and Sb atoms into diffused crystals of Si-0. 1% As, Si-0. 4% As and Si-0. 1% Sb has been studied by backscattering of 1-2 MeV He** plus ions. The maximum displaced fraction and the initial displacement rate varied with irradiation temperature, reaching a maximum at approximately 420 K for the Si-0. 1% As crystal. The displaced fractions of As and Sb atoms were reduced by irradiation at 30 K after initial irradiation at 293 K. The results indicate that the solute atom displacement was cuased by the trapping of several vacancies at each solute atom.
