Quasi-crystal-chemical formulas that take into account the generation of point defects and defect complexes have been proposed for nonstoichiometric, self-doped, and oxygen-doped n- and p-type ZnSe crystals. The defect densities and electron, hole, and Hall carrier concentrations have been evaluated as functions of nonstoichiometry and dopant (Zn, Se, and O) concentration, and conditions have been identified for producing zinc selenide with a given conductivity type and tailored carrier concentration. © 2011 Pleiades Publishing, Ltd.

The formation energies of point defects in II-VI crystals have been evaluated from Hall measurement results and calculated by a thermodynamic method and the extended Hückel method. The energies obtained by different techniques are in satisfactory agreement with each other and with data in the literature. © 2012 Pleiades Publishing, Ltd.
