Title: Photocathode and method for assembly

Abstract

Technologies are described for methods for fabricating a film component. The methods may comprise sputtering a first film onto a substrate. The first film may include a semiconductor compound material. The semiconductor compound material may include a semi-metal material and one or more alkali material. The methods may further comprise evaporating a second film onto the first film. The second film may include the one or more alkali materials. The one or more alkali materials may catalyze crystallization of the semiconductor compound material in the first film substantially throughout the first film to form the film component in the first layer.
