Abstract

An isotropic optically detected magnetic resonance (ODMR) having a Lorentzian lineshape at g - 2.050 ± 0.003 and linewidth (FWHM) of 67.3 mT is observed in GaP doped with 6 - 9 × 1017 S/cm3. The ODMR at g - 2.050 is believed to arise from free electrons (or holes) in the conduction (valence) band. This ODMR is completely quenched due to non-radiative recombination in the vicinity of g - 1.99.
