The decrease in Pr can be attributed to the formation and thickening of the tetragonal (T-) phase interface layer, which reduces the electric field applied to the orthorhombic (O-) phase layer. The subsequent increase in Pr is caused by oxygen defects and leakage current in the T-phase interface layer, raising the electric field applied to the O-FE layer. Therefore, fluctuations in the electric field applied to the O-FE layer are considered as the primary cause for Pr fluctuation. Our direct characterization of T-layers, defects, and electrical properties offers insights into assessing FE phase stability and oxygen defect evolution in fluorite-type FE materials, guiding strategies to enhance device reliability.","PeriodicalId":13198,"journal":{"name":"IEEE Electron Device Letters","volume":"45 10","pages":"1788-1791"},"PeriodicalIF":4.1,"publicationDate":"2024-08-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142368579","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
