摘要：

Molybdenum oxide films were obtained at 200 degreesC by Chemical Vapor Deposition of Mo(CO)(6) at atmospheric pressure and at an optimal ratio of precursor vapors and oxygen. Vibrational and optical properties as dependent on process temperatures were investigated by Raman and Ellipsometric Spectroscopy. The as-deposited films are generally amorphous. A crystallization starts if films are heated at 200 degreesC up to 500 degreesC. Besides the basic Mo-O bands, after annealing a variety of additional vibrational bands was observed. This evidence for polycrystalline structure was also supported by the optical gap energy values found in the range of 2.72-3.63 eV typical for polycrystalline material.
