Summary: | In order to reveal the origin of the 1.40–1.42 eV band which is peculiar to Si-doped GaAs, elaborate investigations of photoluminescence spectra in irradiated and heat-treated Si-doped samples were carried out mainly at 77K. All experimental evidences supported the assignment that the band was caused from a complex of Si atom on As site with As vacancy. Unidentified emission bands at 1.305 and 1.44 eV were observed respectively in (Te + Si)-doped samples subject to electron irradiation and Si-doped samples fired in a dissociation As pressure. |
