The origin of the p-type doping problem in ZnSe is still controversial
in spite of the numerous models presented. We have studied the electr
onic and structural properties of various nitrogen-related defects in
ZnSe using the pseudopotential total-energy methods. The role of the d
efect complexes formed by nitrogen impurities and native defects in ac
ceptor compensation is discussed. (C) 1997 Elsevier Science S.A.
