摘要: A set of semiempirical expressions for the two-center integrals which show explicit dependence these quantities on atomic characteristics, dielectric constant, ionicity solid, and also interatomic separations is constructed II–VI compound semiconductors. The Slater-Koster parameters are then from integrals. band structures various zinc cadmium compounds obtained compared with other theoretical calculations experimental photoemission results. Fur II–VI-Verbindungshalbleiter wird ein Satz von halbempirischen Ausdrucken fur die Zweizentrenintegrale konstruiert, der explizit Abhangigkeit dieser Grosen den atomaren Eigenschaften, dielektrischen Konstante, Ionizitat des Festkorpers sowie interatomaren Abstanden beschreibt. Aus diesen werden dann Slater-Kosterparameter berechnet. Die Bandstrukturen verschiedener Zink- und Kadmiumverbindungen erhalten mit anderen theoretischen Berechnungen experimentellen Photoemissionsergebnissen verglichen.
