With CMOS rapidly approaching fundamental limits, the \"microelectronics revolution\" is threatened. A way to reinvigorate logic technology is to introduce new channel materials with improved transport properties. In this, III-V compound semiconductors and, in particular, InGaAs with high InAs compositions are very promising. This paper reviews the merits and challenges of III-V's for logic applications. It also summarizes recent work of the authors in investigating the logic suitability of InGaAs HEMTs.","PeriodicalId":352388,"journal":{"name":"2007 IEEE 19th International Conference on Indium Phosphide & Related Materials","volume":"7 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2007-05-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114929227","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}

The Tl incorporation increased with the increase of Tl flux in the case of DQW structures with TlGaAs barriers.
