What is Raman study of β‐Sr~0.33~V~2~O~5~ micro‐crystals under high pressure about?

## Abstract The 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‐Sr~0.33~V~2~O~5~ by Raman spectroscopy at different temperatures under high pressure up to 5.7 GPa. The material, which undergoes a metal–insulator phase transition at __T__~MI~ ≈ 165 K associated with charge ordering, consists of a V~2~O~5~ framework of three kinds of infinite double chains along the __b__‐axis with three different sites, V~1~, V~2~ and V~3~, 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 V~2~O~5~ 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 iss
