  • METHODS FOR SUBLIMATION OF Mg AND INCORPORATION INTO CdTe FILMS TO FORM TERNARY COMPOSITIONS
    Publication number: 20120322198
    Abstract: A method for sublimating a thin film of Magnesium (Mg) on a semiconductor structure for improved efficiency is described. One embodiment includes a method comprised of providing a semiconductor substrate in a vacuum chamber, wherein the substrate comprises a window layer and an absorber layer made of CdTe. The method further includes heating the substrate to a diffusion temperature or greater followed by depositing a Mg film on the absorber layer using a sublimation process, wherein at least a portion of the Mg forms a Cd1-xMgxTe alloy within the absorber layer.
