Abstract
High-temperature oxidation of SnSe in the temperature interval 25 to 650‡ C has been studied by X-ray photoelectron spectroscopy, X-ray diffraction and thermal analysis techniques. Exposure to dry oxygen (760 torr pressure) at up to 200‡ C leads to the formation of SnO2 on the surface. The high-temperature bulk oxidation between 250 and 650‡ C goes through distinct steps of formation of intermediate tin oxoselenides, presumably SnOSe or SnSeO2 and its subsequent conversion to SnO2.
