As a result, the temperature conditions for occurrence of physical and chemical activated adsorption are established. With regard to the results of IR spectroscopy, the studies of acid-base properties of the surfaces of the system components, and their charging under conditions of adsorption, the ideas are substantiated about the nature of active centers, the role of which is taken by surface coordinately unsaturated atoms (primarily In and Zn atoms) and about the donor-acceptor mechanism of gas adsorption with gases participating as acceptors. Increased activity of the surfaces of the system semiconductors with respect to basic gases, which is confirmed unambiguously by the direct adsorption studies, and also the change in electrical conductivity under conditions of adsorption even at room temperature have been the basis for recommending the studied semiconductors to be used for fabricating the corresponding low-temperature sensors.</p></div></div>","PeriodicalId":586,"journal":{"name":"Inorganic Materials: Applied Research","volume":"13 4","pages":"1089 - 1093"},"PeriodicalIF":0.75,"publicationDate":"2022-07-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"4753335","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
