Optically detected magnetic resonance of deep centers in molecular beam epitaxy ZnSe:N

Optically detected magnetic resonance has been used to investigate the deep level recombination processes in p-type ZnSe grown by molecular beam epitaxy and doped with nitrogen. In addition to the well-known shallow donor resonance at g=1.11, an anisotropic deep donor resonance is observed with g=1.38 and a deep acceptor resonance is detected at g=2. These results are consistent with the pair recombination processes proposed by us previously where the compensating deep donor was assigned to the VSe-Zn-NSe complex.
