Electrical and luminescent properties of gallium phosphide with radiation defects

  • Published:
Soviet Physics Journal Aims and scope

Abstract

The energy spectrum of local levels and the effect of radiation damage on intensity and character of cathode luminescence lines in the visible region of the spectrum in gallium phosphide single crystals prepared from a solution-melt by the Chochralski method are examined. It is shown that as a result of irradiation by fast electrons with Ee=1 Mev and Co 60 γ-quanta, both donor and acceptor centers are introduced into the original crystals. New radiation centers producing lines in the spectral range studied (500–600 nm) were not observed after irradiation.
