The density of valence states of the II-VI compounds ZnSe, CdS, and HgS has been determined with far uv (h v = 21.1 and 40.8 eV) photoemission. Discrepancies in the widths of the top portions of the valence bands between theory and experiment, similar to those reported for other II-VI compounds in part I, are also found here. The results for ZnSe are compared to those obtained by others using synchrotron radiation and monochromatized X-rays.

Abstract

Es wurden die Valenzbandzustandsdichten der II-VI-Verbindungen ZnSe, CdS und HgS durch Photoemission im fernen UV (h v = 21,1 und 40,8 eV) bestimmt. Widersprüche in den Breiten der oberen Teile des Valenzbandes zwischen Theorie und Experiment, die denen ähnlich sind, die für andere II-VI-Verbindungen in Teil I berichtet wurden, wurden auch hier gefunden. Die Ergebnisse für ZnSe werden mit denen vergliehen, die von anderen Autoren mit Synchrotonstrahlung und monochromatisierten Röntgenstrahlen erhalten wurden.
