The analyses employs a three dimensional simulation of Silicon nanowire transistor based on self consistent solution of Poisson, Schrodinger equations. Quantum mechanical transport model uses the non equilibrium Green's function (NEGF) [1] while the semi classic model doesn't account for tunneling current. We investigate the effect of tunneling current on I-V characteristics of Nanowire transistor with the different channel length. We have used of NANO TCAD ViDES software to analyze a DG (double gate) silicon nano wire transistor. We get that when the channel length increases to20nm and upper, tunneling is significant only for inversion condition, while for low gate voltages the error between these two models is negligible.","PeriodicalId":6390,"journal":{"name":"2010 3rd International Nanoelectronics Conference (INEC)","volume":"10 1","pages":"602-603"},"PeriodicalIF":0.0,"publicationDate":"2010-03-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"78399332","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}

By integrating plasmonic structures on active optical devices, one can engineer and fabricate devices with small footprints and special beam profiles in the near-field and/or in the far-field.

GaN and AlN single-layer films are also synthesized for comparison. It is found that the turn-on field of the GaN/AlN two-layer films are considerably decreased 2 orders of magnitude than that of single-layer films. The improvement of FE characteristics an attributed to the quantum structure effects, which supplies a favorable location of electron emission and enhances tunneling ability. We show that by tuning the thickness of GaN/AlN, various FE characteristics can be obtained, which is induced by the modulation of quantum potential well/barrier structure.

Si substrates were covered with predeposited ZnO films as seed layers, which were deposited by DC magnetron sputtering. A growth mechanism involving nanorods were built from tiny nanowires of smaller diameter fusing together was inferred from SEM study of ZnO nanorod arrays. Also, growth positions of ZnO nanorod arrays were easily controlled via coating the ZnO seed layer with patterned photoresist “mask” fabricated by conventional photolithography. ZnO nanostructures would not grow on the organic mask due to the lack of ZnO nucleation sites on the organic resist layer.
