Numerical program developed to implement this algorithm, provides to operators all the particulars of gas and an indicator of credibility of the results provided as a measure of the degree of disturbance of the signals received from sensors.","PeriodicalId":377326,"journal":{"name":"CAS 2010 Proceedings (International Semiconductor Conference)","volume":"56 10","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-12-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"120901790","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}

Our calculations based on non-equilibrium Green function formalism show that a single band model with tunneling light electrons in Si is quantitatively sound in simulating Si based RTD's. It is found that light electrons contribute not only through 2-dimensional (2D) transverse density of states but also through the transparency of the barriers. Thus a single-band model can be safely used in applications.","PeriodicalId":377326,"journal":{"name":"CAS 2010 Proceedings (International Semiconductor Conference)","volume":"36 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-12-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124581115","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}

Simulation results provided a 3.3 dBc/Hz improvement from −105.3 dBc/Hz to −108.6 dBc/Hz at a 1 MHz offset frequency from the 5 GHz carrier. Measured results confirm the correlation of phase noise performance between simulation and prototype.

For this purpose we have grown self standing blocks of multi-wall CNTs (MWCNTs). The blocks were subsequently back-contacted and encapsulated into epoxy resin for their use as voltammetric electrodes. A ruthenium-complex solution has been used as ECL label. It has been observed a periodical light emission that lasts for hundreds of cycles, likely due to the CNTs structure. Thanks to a dataprocessing algorithm which exploits this behaviour, the experiments show that it is possible to obtain a great increase in detection limit.","PeriodicalId":377326,"journal":{"name":"CAS 2010 Proceedings (International Semiconductor Conference)","volume":"53 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-12-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114525281","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}
