Electronic Instabilities of Two-Dimensional Metals K3Cu8S6 and Rb3Cu8S6
Abstract
The two-dimensional metals K3Cu8S6 and Rb3Cu8S6 show anomalies in their temperature dependent electrical conductivities which suggest charge- density waves. The band structure calculation of the mixed-valence CDW compound K3Cu8S6 shows that the Fermi surface of the compound is mainly composed of sulfur p electrons. The results of the calculations are supported by XPS studies. Keywords: Charge-density waves/electrical conductivity/alloys; Band structure calculation/mixed-valence/fusion; Reaction/oxidation/states/Fermi surface.
