Title: Surface passivation process of compound semiconductor material using UV photosulfidation

Patent ·
OSTI ID:870072

A method for passivating compound semiconductor surfaces by photolytically disrupting molecular sulfur vapor with ultraviolet radiation to form reactive sulfur which then reacts with and passivates the surface of compound semiconductors.
