Abstract

A deep photoluminescence (PL) band peaking at 1.08 eV in Cu-doped GaP has been studied by means of optically detected magnetic resonance (ODMR). We report an intense S=l ODMR spectrum arising from this PL band. The signal is strongly anisotropic and consistent with a center of triclinic symmetry. Some of the ODMR transitions show a well resolved hyperfine structure in agreement with the nuclear spin I=3/2 of Cu, thus suggesting the presence of Cu in the defect.
