Abstract

The energy bands of KCl, KBr, and KI have been calculated using the relativistic Green's function (KKR) method. Besides the results of calculations with atomic potentials for KCl, KBr, and KI results for KI from ionic potentials with Kohn‐Sham and Slater exchange potentials are also compared. Special care is taken to interpret the excitonic structure of KI in terms of band separations. For this purpose extreme ultraviolet data are used to confirm the interpretation.
