The present invention is related to methods and apparatus that allow a chalcogenide glass such as germanium selenide (GexSe1-x) to be doped with a metal such as silver, copper, or zinc without utilizing an ultraviolet (UV) photodoping step to dope the chalcogenide glass with the metal. The chalcogenide...http://www.google.com/patents/US7446393?utm_source=gb-gplus-sharePatent US7446393 - Co-sputter deposition of metal-doped chalcogenides
