ABSTRACT:
A method of forming a hydrogenated amorphous germanium carbon (a-GeCx:H) film on a surface of an infrared (IR) transmissive material such as a chalcogenide is provided. The method includes positioning an IR transmissive material in a reactor chamber of a parallel plate plasma reactor and thereafter depositing a hydrogenated amorphous germanium carbon (a-GeCx:H) film on a surface of the IR transmissive material. The depositing is performed at a substrate temperature of about 130° C. or less and in the presence of a plasma which is derived from a gas mixture including a source of germanium, an inert gas, and optionally hydrogen. Optical transmissive components, such as IR sensors and windows, that have improved abrasion-resistance are also provided.
