Two distinct spin splitting peaks can be observed at current-voltage (I-V) characteristics at low temperature. The spin polarization decreases with the temperature due to the thermal effect of electron density of states. When charge polarization effect is considered at the heterostructure, the spin polarization is enhanced significantly. A highly spin polarized current can be obtained depending on the polarization charge density.","PeriodicalId":6406,"journal":{"name":"2008 IEEE International Conference on Semiconductor Electronics","volume":"10 1","pages":"325-328"},"PeriodicalIF":0.0,"publicationDate":"2008-12-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"77321564","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 Telemedicine need the development of various tools for home analysis, in order to send all the collected analysis to a medical center or to a database on Internet. In this paper is proposed a simple and cheap platform for the Electro-cardio-gram recording on the Personal Computer. The platform consists in a hardware part and a software part. The general electrical circuit for the ECG recording was adapted in order to be available at home applications. The amplified signal is then connected via the microphone muff to PC. A dedicated software converts the input ldquonoiserdquo signal into an ECG trace. In this way, the ECG becomes available, in the simpler mode directly on the computer screen, without any expensive tracer.","PeriodicalId":6406,"journal":{"name":"2008 IEEE International Conference on Semiconductor Electronics","volume":"10 1","pages":"433-436"},"PeriodicalIF":0.0,"publicationDate":"2008-12-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"75082080","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 copolyimides containing naphthalene and flexible hexafluoroisopropylidene groups were soluble in polar amidic solvents and their solutions gave flexible thin films when spread onto glass plates and very thin films with smooth surface by spin coating.
