Abstract
AbstractThe cover picture of the current issue relates to the article by A. G. Kontos et al. [1]. The authors study the phonon dynamics of the strontium vanadium oxide bronze β‐Sr0.33V2O5 by Raman spectroscopy at different temperatures under high pressure up to 5.7 GPa. The material, which undergoes a metal–insulator phase transition at TMI ≈ 165 K associated with charge ordering, consists of a V2O5 framework of three kinds of infinite double chains along the b‐axis with three different sites, V1, V2 and V3, for vanadium atoms in six‐fold octahedral and five‐fold coordination, respectively. The Sr cations are located at the sites in the tunnel formed by the V2O5 framework. The corresponding author Yannis S. Raptis is Associate Pro‐ fessor at the Physics Department of the National Technical University of Athens (NTUA). His research interests include the study of optical and lattice‐dynamic properties of materials and their pressure dependence.The article is a presentation from the 12th International Conference on High Pressure Semiconductor Physics (HPSP‐12) held in Barcelona, Spain, 31 July–3 August 2006 whose proceedings are published in this issue of physica status solidi (b).
