X-Ray Photoelecton Spectra and Electronic Structure of Bi2S3 Crystals

232_02/2002In this issue's paper [1] selected as Editor's Choice, experimental results of X-ray photoelectron spectroscopy of valence band and core levels of Bi2S3, a highly photoconductive semiconductor material, are compared with the results of theoretical ab initio calculations. These are based on the molecular model of the Bi2S3 crystal, as depicted in the cover picture of this issue. At room temperature, the crystal exhibits weak polarity. Anomalies of various physical properties such as a small charge redistribution and phase transitions are detected in the temperature range 160–460 K.The corresponding author, Jonas Grigas, is professor at the Department of Radiophysics of Vilnius University, where he is working on dielectric and other spectroscopies of ferroelectrics and various related materials.
