In this work, we systematically investigated the effect on structure and electrochemical properties brought by W doping on Fe site of LiFePO4. LiFe1-yWyPO4 (y = 0. 0.01, 0.02, 0.03) samples with carbon coating were prepared by using solid-state reaction. The phase and structure of as prepared powders were characterized by X-ray diffraction. Cycling charge and discharge measurement at various C-rates, cyclic voltammetry and electrochemical impedance spectroscopy were employed to reveal the electrochemical properties. Results showed that carbon coating dramatically improved the capacity at fast C-rate. The sample with 2% W doping and carbon coating was observed to have the highest charge capacity of 146 mAhg-1 at 0.1C and 110 mAhg-1 at 1C.","PeriodicalId":189707,"journal":{"name":"2013 13th IEEE International Conference on Nanotechnology (IEEE-NANO 2013)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115679197","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 fabrication is based on electron-beam lithography in combination with a two-step tetramethylammonium hydroxide (TMAH) wet etch. We optimized the etching profile of the TMAH process on silicon-on-insulator <;100> using isopropanol additive and temperature regulation, yielding very low and controllable etching rates and enabling the formation of ultra-smooth silicon morphology. The optimized TMAH etching process was confined using photolithography to the middle sections of silicon nanowire channels to achieve localized step-etching of the nanowires. The thinned silicon nanowires were addressed via metal contact lines in the final step of the fabrication. Preliminary current-voltage characterization in liquid demonstrated a p-channel field effect transistor behavior in depletion mode with a very high output current and negligible contact resistance. The proposed process provides an alternative route for reliable and reproducible fabrication of ultra-thin silicon nanowire devices.","PeriodicalId":189707,"journal":{"name":"2013 13th IEEE International Conference on Nanotechnology (IEEE-NANO 2013)","volume":"32 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114536270","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 root-mean square roughness measured by AFM was 9.07 nm for the nano-bumpy Pd structure whereas that of the simple Pd thin film was 0.98 nm. At hydrogen gas concentration of 2,000 ppm, the sensitivity of the simple Pd thin film and the Pd nano-bumpy film was 0.638 and 1.045, respectively. The sensitivity of the Pd nano-bumpy film was much higher than that of the Pd thin film due to the very high surface-to-volume ratio of the nano-bumpy Pd structure.","PeriodicalId":189707,"journal":{"name":"2013 13th IEEE International Conference on Nanotechnology (IEEE-NANO 2013)","volume":"163 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123157296","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 relatively large lateral parasitic capacitances from the gate electrode to the regrown source and drain regions are quantitatively determined to estimate their impact on the transistor's RF performance. The current gain cut-off frequency fT of such a transistor is estimated to be about 320 GHz using small-signal equivalent circuit model calculations. With the significantly reduced parasitic series resistances due to the regrown source and drain structures, the maximum frequency of oscillation fmax can attain up to 530 GHz. The parasitic circuit elements are identified to have varying degree of impact on the RF performance.
