It was found that short-term (1 min) low-energy treatment with argon and hydrogen ions does not lead to changes in the parameters of laser diodes, while treatment with nitrogen ions results in a decrease in the maximal output power and an increase in the probability of catastrophic optical damage. It is also shown that the use of an ion source based on electron cyclotron resonance leads to better results compared to a End Hall source or radiofrequency source with inductively coupled plasma, due to the lower energy of the ions.","PeriodicalId":24054,"journal":{"name":"Физика и техника полупроводников","volume":"10 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"82830498","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}

To create diodes with the characteristics required for operation, it is necessary to understand the mechanisms of current transport in both dielectrics and their contacts with metals. To solve this problem, it is necessary to develop an algorithm for dividing the general current-voltage characteristic into characteristics of individual contacts, the analysis of which will also allow us to investigate the problems of the properties of defects in the dielectrics that make up the diode. In this paper, the solution of the above problems is presented on the example of the Al-Al2O3-Ta2O5-Ni diode. The authors showed how one can divide the current-voltage characteristic into components, calculate potential barriers at the boundaries of metals with contacting dielectrics, and determine the concentration and energy characteristics of structural defects in dielectrics.","PeriodicalId":24054,"journal":{"name":"Физика и техника полупроводников","volume":"110 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"87693329","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}
