The modelling utilizes the first order quadratic equations for the MOS transistor. In order to validate the analytical model, a Verilog-A model was written using the same MOS equations, and later matched to the ibm 130nm technology node resulting in a satisfactory approximation, with relative errors within 15%. Analysis of the ETP control voltage, pseudo-resistor current and pseudo-resistor resistance using the simple model were performed as a function of body factor. When the body factor decreases (better gate to channel electrostatic coupling) the pseudo-resistance increases for the same silicon chip area.","PeriodicalId":112590,"journal":{"name":"2021 IEEE Latin America Electron Devices Conference (LAEDC)","volume":"4 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-04-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134043301","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}

Numerical simulations were performed using Sentaurus TCAD device simulator. The presence of different biomolecules, in the LUS region, affects the drain current of the on-state (IOn). It is shown that the sensitivity of the Bio-nTFET increases 3 orders of magnitude from k = 1 to k = 10 due to the improved fringing field that reduces the tunneling length resulting in a higher tunneling current. The sensibility also increases for a higher values of QBio. The highest sensitivity value obtained in this work was 6.103 A/A for QBio = 1.1012 cm-2 and k = 10. The proposed device shows great potential as a biosensor based on TFET devices.","PeriodicalId":112590,"journal":{"name":"2021 IEEE Latin America Electron Devices Conference (LAEDC)","volume":"23 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-04-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115359296","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}

Impact of hot carrier degradation through DC, small, and large signal performance is studied.

There is an urgent need to harness this effect at a minimum supply voltage (VA). Therefore, in this paper, we have investigated the transient NCS response in a series resistor (R)-organic FE (OFE) (RCOFE) circuit at ±0.4 V employing a well-calibrated multidomain Ginzburg-Landau-Khalatnikov model in Sentaurus technology computer-aided design (STCAD) environment. A remarkable average coercive voltage reduction of about 69 to 90.16 % is achieved concerning different literature reports. The proposed OFE gate stack (OFEGS) can capture the NCS effect even at ±0.4 V, while its counterpart FE hafnium dioxide (HfO2) based gate stack fails to harness the NCS and behaves like a positive linear capacitor. The various influence of the Landau parameters, R, and switching resistivity (ρOFE) on the transient NCS behavior are significantly investigated. We found that the NCS response time (δt) and the NCS voltage window (δVNCS) accentuate as R increases. The δt in the proposed OFEGS is much faster (99.77 to ~99.88 %) than its state-of-the-art counterparts. Finally, our OFEGS can capture the maximum δVNCS by coming close to the ideal Landau path with a negligible deviation of about ±0.009 V at zero FE polarization. Therefore, the proposed device capturing NCS with a small VA of ±0.4 V, total switched charge density of 2.54 µC/cm2, and lower energy dissipation of 0.95 fJ could act as a rescuer for many standard transistors from the Boltzmann’s Tyranny.","PeriodicalId":112590,"journal":{"name":"2021 IEEE Latin America Electron Devices Conference (LAEDC)","volume":"44 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-04-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123199423","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}
