METHOD TO PRODUCE PYRITE

摘要

A method for preparing a device having a film on a substrate is disclosed. In the method, a film is deposited on a substrate. The film includes a single- crystalline or poly-crystalline semiconducting thin film. The single-crystalline or poly-crystalline semiconducting thin film is formed by sequential evaporation of a first and a second element. One example device prepared by the method includes a silicon substrate and a film on the substrate, wherein the film includes semiconducting and single- or poly-crystalline pyrite as the compound.
