Hence, a Ge epilayer with lower TDD can be realized and useful for subsequent III-V integration and device fabrication.","PeriodicalId":371483,"journal":{"name":"2014 7th International Silicon-Germanium Technology and Device Meeting (ISTDM)","volume":"63 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-06-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127011064","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 obtained 2DHG mobility is substantially higher than those reported so far and in structures grown by research type epitaxial growth techniques, i.e. SS-MBE and LEPE-CVD. Also, the room and low temperature hole mobilities obtained are the highest not only among the group-IV Si and Ge based semiconductors, but also among p-type III-V and II-VI ones. These results demonstrate the very high quality of the strained Ge QW epilayers grown by RP-CVD and the huge potential for further applications of such materials in modern and future CMOS, p-MOSFET and p-MODFET electronic devices. The 2DHG mobility is already sufficiently high to fabricate sub-100 nm electronic devices and demonstrate ballistic transport therein at or around room temperature.","PeriodicalId":371483,"journal":{"name":"2014 7th International Silicon-Germanium Technology and Device Meeting (ISTDM)","volume":"83 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-06-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129343106","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}
