Gas sensor on base of vitreous chalcogenide semiconductors

摘要

the invention relates to semiconductor devices, in particular gas detectors and can be used for detection of toxic gas in the atmosphere.gas detector based on semiconductor halcogenici glassy contains a support insulator, on which are located a layer sensitive to gas consecutively in a semiconductor halcogenic vitreous base obtained by the method evaporarii in vacuum as2s3, as2se3 or their solutiilor solid, and two electro day.also sensitive to gas layer has a surface with a reliefata strict periodicity, executed in the form of network difractie by holographic method.
