Thermodynamics and Crystal Defect Subsystem Zinc Telluride Crystals ZnTe (Review)
Journal Title: Фізика і хімія твердого тіла - Year 2014, Vol 15, Issue 3
Abstract
On the basis of quantum-chemical methods defined characteristic features zinc telluride crystals: formation energies ΔE, enthalpy of formation ΔH, entropy ΔS, and Gibbs energy ΔG heat capacity at constant pressure Cp and constant volume Cv. The analytical expressions for their temperature dependences. The method of thermodynamic potentials and Quasi-Chemical Reactions of point defects studied ZnTe crystal defect subsystem in terms dvotemperaturnoho annealing in a couple of components. Calculated concentration of point defects and free carriers depending on the annealing temperature T and the partial vapor pressure components PZn, .Znaydeno the constants quasichemistry reactions of defects in zinc telluride. Using Crystal formula shows that the dominant material defects for p-type (p-ZnTe) are zinc vacancies and interstitial tellurium.
