Abstract
Optically detected magnetic resonance (ODMR) of heavily nitrogen‐doped ZnSe at 24 GHz reveals an anisotropic spectrum which can be assigned to a deep donor comprised of a Se vacancy paired with an impurity. The newly resolved spectrum is trigonal along 〈111〉 with g∥=2.0072(2) and g⊥=2.0013(2). Comparison of this g tensor with previous work leads to the assignment of the spectrum to VSe‐X, where X is most probably Cu or Ag. Combining this result with previous photoluminescence and ODMR work shows that ZnSe:N has three distinct donors which include both impurities and intrinsic defects.Keywords
