The electrical conductance of CuTCNQ are then modified by graphitic oxide (GO) by dispersing it onto film of CuTCNQ nanorods. The conductance of the nanorod film is increased by approximately one order in magnitude. Increase in conductance occurs due to electronic charge transfer from graphitic oxide to CuTCNQ, which has been corroborated from the observed frequency shift of C≡N stretching mode, as seen in Fourier Transform Infrared Spectroscopy (FTIR).","PeriodicalId":186054,"journal":{"name":"2014 IEEE 2nd International Conference on Emerging Electronics (ICEE)","volume":"9 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124072666","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}

Lack of area-specific forecasts for the power output of grid-connected photovoltaic system hinders tapping solar power on a large scale. The objective of this paper is to estimate the profile of produced power of a grid-connected 20 kWp solar power plant in a reputed manufacturing industry located in Tiruchirappalli, India [10° 44' 42.3816\" N, 78° 47' 9.4524\" E]. An Artificial Neural Network (ANN)-based model is proposed in this paper. An experimental database of solar power output (from 7th January 2014 to 10th February 2014) has been used for training the ANN. Simulations were carried out with the Neural Network Fitting Toolbox of MATLAB software. Day-Ahead Forecasting results indicate that the proposed model performs well with great accuracy and efficiency. Statistical error analysis in terms of Mean Absolute Percentage Error (MAPE) was conducted and the best result was found to be 0.2887%. Reliable area-specific solar power production map can provide better utilization of solar energy resource and help in power system management.","PeriodicalId":186054,"journal":{"name":"2014 IEEE 2nd International Conference on Emerging Electronics (ICEE)","volume":"39 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129173332","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 effects of spacers on both sides of high-k gate oxides are also studied for the device performance parameters, namely: drain current (ID), ON-state current (ION), threshold voltage (VT), subthreshold slope (SS) and drain-induced barrier lowering (DIBL). SS and DIBL are improved for the device in which spacer dielectrics are included.

Based on the DOE results, a further set of four samples was prepared to modulate deposition rate and stoichiometry. Material characterization of these samples using Fourier transform infrared spectroscopy (FTIR), X-ray photolectron spectroscopy (XPS), surface profilometry and ellipsometry is presented. Further, to determine the mechanical properties, cantilevers were fabricated and characterized using scanning electron microscopy (SEM) and laser Doppler vibrometry (LDV).
