Processing and characterization of GaAs surface-barrier heterostructures with texturized interface

The possibility to control photosensitivity of Au(ITO)/GaAs surface-barrier heterostructure by evaporated processing including texturation and passivation of interface on investigated. The complex method of their characteristic is proposed that included analysis of optical, electrical and photoelectric characteristics of structure. The obtained results allowed to determine the change of optical and recombination parameters of interface caused by investigated processing.
