In nanoscale devices, the dopant states under high built-in electric field may significantly affect inter-band tunneling transport. Here, we introduce firsttime observations from measurements of nanoscale Si tunnel diodes of two main effects: (i) splitting of dopant minibands in high electric field, similarly to the Wannier-Stark ladder; (ii) single-charge tunneling transport via donor-acceptor pairs aligned by the electric field. These phenomena produce distinguishable effects to enhance inter-band tunneling current.","PeriodicalId":424135,"journal":{"name":"2017 Silicon Nanoelectronics Workshop (SNW)","volume":"150 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122464069","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 use of graphene in conventional semiconductor circuits has proved difficult due to its negligible bandgap.

Simulation results are presented for a GBDT-based inverter and full adder that are predicted to operate twice as fast as conventional CMOS circuits, at the cost of much lower transistor density. The GBDT-based circuits presented in this paper would be well suited for high-speed, high-duty-cycle applications, including high-throughput networking and high-performance computing.","PeriodicalId":424135,"journal":{"name":"2017 Silicon Nanoelectronics Workshop (SNW)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125841317","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 novel interband tunneling transport mechanism of tunnel-TFT results in special PBTI behavior. For PBTI at 75 °C with stress voltage 10 V, tunnel-TFT exhibit excellent PBTI immunity compared to conventional TFT. However, the degradation of tunnel-TFT is getting worse when the temperature of PBTI is reduced. It may be because the interband tunneling is more sensitive at low temperature due to the deep trap characteristics, which affects the transport behavior of tunneling electrons. It would be helpful for the development of tunnel transistors.","PeriodicalId":424135,"journal":{"name":"2017 Silicon Nanoelectronics Workshop (SNW)","volume":"113 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115192043","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}
