Methods for forming thin films comprising tellurium

Methods for controllably forming Sb-Te, Ge-Te, and Ge-Sb-Te thin films are provided. ALD processes can be used to deposit a first film comprising ZnTe. Providing an antimony source chemical, such as SbI3 replaces the zinc, thereby forming Sb2Te3 thin films. Ge-Te and Ge-Sb-Te films can also be made...

description Methods for controllably forming Sb-Te, Ge-Te, and Ge-Sb-Te thin films are provided. ALD processes can be used to deposit a first film comprising ZnTe. Providing an antimony source chemical, such as SbI3 replaces the zinc, thereby forming Sb2Te3 thin films. Ge-Te and Ge-Sb-Te films can also be made by providing Ge sources to ZnTe and Sb-Te thin films, respectively.
