X-ray scattering study of charge-density waves inK3Cu8

Electrical properties of β-BaCu2S2

“…unique properties such as a metallic behavior, unlike oxides of which many are insulators [8][9][10][11]. Additionally, the copper-containing chalcogenides exhibit a large variety of crystal structures and phase transitions [12,13]. One of the unique crystal structures is a layered structure (natural superlattice structure).…”

Transport and Magnetic Studies of New Mixed-Valence Compounds: K3Cu8Se6, KCu3Se2, K3Cu8Te6and BaCuS3-x

“…The studies reported in this paper were stimulated by the finding that the layered K3Cu8S6 exhibited a CDW phenomenon [1,2,4] which is typical of low-dimensional metals. The K3Cu8S6 compound is the first inorganic material where the charge carriers and the subsequent CDW phenomenon have significantly p character (i.e.…”

“…The mixed-valent compounds have been of particular interest and subject to numerous physical investigations because they exhibit such properties as metallic conductivity, superconductivity and charge-density waves (CDW) [1,2].…”

Thiocuprates—Interesting anisotropic solids

“…Because of the low-dimensional metallic character of these compounds their properties attracted much attention. K 3 Cu 8 S 6 exhibits two low temperature phase transitions: a second order one to an incommensurate modulation at 153 K and a first order one at 55 K [72,73]. Theoretical [69] and experimental studies on these phase transitions were reported in several papers [74][75][76].…”
