Method for enhancing stability of N-type semiconductor through oxygen elimination

Abstract

A method for enhancing the stability of an N-type semiconductor through oxygen elimination includes constructing an antioxidant layer on the surface of a semiconductor material, or blending the antioxidant with the N-type semiconductor material. The antioxidant removes the existing oxygen and related species in the N-type semiconductor, eliminates the related trap state, and prevents the N-type semiconductor from further degrading, so that the electrical properties such as mobility of the N-type semiconductor device are improved, and the operation stability and long-term storage stability are improved. In addition, the antioxidant also inhibits the photobleaching of N-type semiconductors and significantly improves the photochemical stability of N-type semiconductors.
