Deposition of Gadolinium Cerium Oxide

Thin films of Gadolinium Cerium Oxide (Gd0.2Ce0.8O2) can be deposited using RF sputtering. In this process, the main parameters are temperature and additional oxygen, which can be adjusted to tailor the properties of the deposited films. The target is a solid ceramic 75 mm (0.125" thickness) GCO target bonded to a Cu plate.
