Abstract
The electronic energy structure of the defect system of c-BNx with ZnS -type structure is calculated in the multiple-scattering theory by the local coherent potential method. The cluster version of the MT approx imation is used to calculate the crystal potential. The effect of the relaxation of the crystal lattice on the electronic structure of nonst oichiometric boron nitride C-BN0.75 is studied and a comparison is mad e with the electronic energy structure of c-BN in the same approximati on.
