Deep electron traps created by gamma-ray irradiation of Au/GaInP Schottky diodes grown by metal-organic chemical vapor deposition (MOCVD) were studied by using deep level transient spectroscopy (DLTS) technique. Three distinct deep electron traps, G1, G2 and G3, were observed in the irradiated GaInP samples. According to the analysis of trap properties in various samples, trap G1 is verified as a bulk defect located at 0.13 eV below the conduction band, while trap G2 and G3 are interface states originated from the junctions of Au/Te-doped GaInP contacts.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
