Our results show that: (a) even a single trap can detereorate the inverse sub-threshold slope (SS) of a nanowire InAs Tunnel FET; (b) the inelastic phonon assisted tunneling (PAT) through interface traps results in a temperature dependence of the Tunnel FETs IV characteristics; (c) the impact of interface traps on Ioff is larger in Tunnel FETs than in MOSFETs; (d) interface traps represent a sizable source of device variability.","PeriodicalId":6376,"journal":{"name":"2012 International Electron Devices Meeting","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2012-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"90278035","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}

These distributions can only be obtained in sufficient detail by the simultaneous solution of the Boltzmann transport equation (BTE) for both carrier types. For predictive simulations, the energy distributions have to be thoroughly resolved by including the fullband structure, impact ionization (II), electron electron scattering (EE), as well as the interaction of minority carriers with the majority carriers. We demonstrate that this challenging problem can be efficiently tackled using a deterministic approach based on the spherical harmonics expansion (SHE) of the BTE.","PeriodicalId":6376,"journal":{"name":"2012 International Electron Devices Meeting","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2012-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"90591478","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}

It consists of a two-step conversion of heat into electricity. The first step is a thermo-mechanical conversion by a bimetal and the second is an electromechanical conversion by a piezoelectric. The first developed prototypes show natural thermal resistance matching between their body and the interface with ambient air, and therefore do not need a heat sink in order to work. The available mechanical power (2.7 mW/cm2 measured in practice for a single bimetal, and extendable to theoretical 27 mW/cm2 for 100 bimetals occupying the same surface) that can be converted into electricity may lead to a superior performance compared to the best commercial Seebeck devices.

We evidence the transistor capability to sustain full forward-body-biasing solution thanks to a planar back-side gate scheme. Silicon measurements on low complexity circuits show that the dynamic power consumption can be reduced by 90% without any speed degradation by simply selecting the appropriate power supply and body bias couple (Vdd; Vbb). A simple switching energy efficiency model is then proposed allowing the (Vdd; Vbb) couple prediction reaching the minimum energy point. Finally, we demonstrate on a full CPU Core implementation with UTBB a total power reduction of -30% and a +40% energy efficiency at identical speed with respect to bulk technology thanks to back side gate biasing efficiency.","PeriodicalId":6376,"journal":{"name":"2012 International Electron Devices Meeting","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2012-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"91414785","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}
