Cathode-ray Investigation of Thin Layers Formed on Some Single Crystals. II. Molybdenum Oxide Deposited on Molybdenite by Sublimation of MoO₃ in Vacuum

Abstract

Thin films of molybdenum oxide were formed by subliming MoO₃ in vacuum on the cleavage face of molybdenite polished surfaces of metals at a temperature t and their strueture was investigated by the method of cathode-ray diffraction. It was found that the strueture depends upon the nature of the base and the temperature t as summarised in the following table. The substance denoted by [MoO₃] in the table is supposed to be an intermediate oxide between MoO₂ and MoO₃ The substance which produced the diffuse rings has not been identified. In the pattern of MoO₂ single crystal, extra spots were observed and they are interpreted as due to a superstructure of MoO₂ crystal
