Synthesis and Some Properties of Metal Organic Chemical Vapour Deposited Molybdenum Oxysulphide Thin Films

of oxygen. The large amount of oxygen was attributed to the large abundance of oxygen in the starting material. A direct optical energy gap of 3.31 eV was obtained from the analysis of the absorption spectrum. The scanning electron microscopy (SEM) micrographs of the fllms showed that the fllms were continuous and porous. An estimated average size of the grains was below 5 „m. X-ray difiraction (XRD) showed that the deposited fllms were crystalline in nature.
