Abstract
HgCdTe epilayers were grown by molecular beam epitaxy. A series of As-implanted CdTe and HgCdTe epilayers annealed under different temperat ures were investigated by photoluminescence spectroscopy. More As+ ion s can occupy the Te sublattice after the samples were annealed at 450 degrees C, and the acceptor level of As+ on the Te sublattice for HgCd Te material (x approximate to 0.39) is 31.5 meV. The Raman spectrum st udy indicates a recovery of the crystalline perfection after the post- As+-implantation thermal treatment.
