Hi dears
The thermal vacuum evaporation method has been utilized to deposit cadmium oxide thin films. The X-ray diffraction data indicated diffraction peaks corresponding to cadmium and no diffraction peaks of cadmium oxide. Is there any help explaining why the cadmium oxide phase does not appear?
Thermal evaporation is not the best method to prepare cadmium oxide it may lead to separation of the constituents thus use pulsed laser deposition or spray pyrolysis to prepare CdO
Dear Dr. Bushra A Hasan
First of all, thank you for your interest. In fact, the work procedure requires using the thermal vacuum evaporation deposition technique. At the same time, I am interested in searching for the absence of oxide phases besides the high vacuum reason.
Thanks again for your interest.
With thermal evaporation you are not guaranteed crystal growth of thin films. A lot depends on the substrate you are depositing onto. To get epitaxial growth from thermal evaporation you generally need a crystalline substrate. If you do have a crystalline substrate then this may affect the diffraction data.
