Our results indicate that the switching characteristics of TiO2-x device are very strongly related with the control of conductive filaments' growth within the dielectric layer, which stems from the local enhancement of the electric field in the vicinity of nanocrystals. This effect in conjunction with the room temperature fabrication process and the forming free nature of the thin films is considered as an optimization route of resistive random access memory design.","PeriodicalId":332857,"journal":{"name":"2015 45th European Solid State Device Research Conference (ESSDERC)","volume":"15 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-11-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126696752","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}

TCAD simulations were used to determine the mechanisms of leakage current generation at specific back-gate potentials. Traps were introduced to study the impact of hot-carrier stress on the leakage current. Location, polarity and density of traps were considered. For a virgin device tunneling is predominant in inversion and accumulation. In full depletion surface generation dominates the leakage behavior. Surface and oxide traps shift the leakage current and alter its mechanism with increasing density, i.e. stress time. In inversion trap generation dominates at the top SOI interface. In depletion top and bottom interface traps are generated.","PeriodicalId":332857,"journal":{"name":"2015 45th European Solid State Device Research Conference (ESSDERC)","volume":"17 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-11-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127547981","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}

Surface plasmon waveguides and detectors are integrated with metal-oxide-semiconductor field-effect transistors (MOSFETs) on the substrate. In the circuits, surface plasmon signals are generated by light at a wavelength at which silicon is transparent, and propagate along the waveguide before being converted into electrical signals by the detector. These electrical signals drive the MOSFETs during both dc and ac operation. The measured performances of these devices indicate that the surface plasmons propagate on the metal surface at the speed of light and drive the electronic devices without any absorption in silicon.","PeriodicalId":332857,"journal":{"name":"2015 45th European Solid State Device Research Conference (ESSDERC)","volume":"10 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-11-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125402712","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}
