History has shown that breakthroughs in science that are rapidly commercialized shape the socio-economic landscape and are of immense importance to prosperity for businesses, governments, and industries. As the economy becomes even more global and competition increases, the ability to forecast the evolution of technology becomes more critical if businesses and countries are to remain competitive. Nanotechnology is a revolutionary science that will contribute to the economic prosperity of the businesses who commercialize the technology early. This paper briefly reviews the commercialization of nanotechnology.","PeriodicalId":408575,"journal":{"name":"Proceedings of the 2nd IEEE Conference on Nanotechnology","volume":"16 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2002-11-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130468666","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}

With the use of new technologies it is possible to observe a state of the cell at different time steps, assemble and disassemble genetic information carriers, etc. With new tools available there is a chance to answer the question that has motivated our predecessors. There is a chance to find out \"how it all works?\" In this paper we study a method of gene networks modelling. A gene network is a mass of genes interacting with one another through expression. The model is used to infer a gene expression mechanism on the basis of gene expression measurements. In our approach we employed two network models: a Boolean network model and an artificial neural network model. We have shown that large data can be handled efficiently with the aid of already developed methods and algorithms. Thanks to them, drawing meaningful inferences from large gene expression data may be converted into simple tasks.","PeriodicalId":408575,"journal":{"name":"Proceedings of the 2nd IEEE Conference on Nanotechnology","volume":"2 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2002-11-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128008317","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}

To compute electron-hole energy states and magnetization, a realistic three-dimensional (3D) model is applied and is solved with the nonlinear iterative method. With the developed nanostructure simulator, the variation of energy states for semiconductor quantum rings (R/sub in/=10 nm) changing into dots (R/sub in/=0 nm) are investigated comprehensively. For a fixed ring height and width, we have found the energy band gap of rings are strongly dependent on ring (and dot) shapes, ring inner radii, and applied magnetic fields. Due to the magnetic field penetration into the ring region, the variation of electron-hole energy states and magnetization of InAs/Gas rings saturate and oscillate nonperiodically when the magnetic field increases. Our observation in the oscillation of electron-hole energy states is contrary to conventional periodical argument. The results presented here provide an alternative in studying optical spectra and magneto-optical property of semiconductor quantum rings and are useful for real device applications.","PeriodicalId":408575,"journal":{"name":"Proceedings of the 2nd IEEE Conference on Nanotechnology","volume":"26 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2002-11-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121454425","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 idea is based on a standing wave enhancement of detector responsivity. The detector contains lateral semiconductor superlattice, broadband bow tie THz antenna and THz resonator. As compared with well-known variant we change a technology of antenna attachment to the superlattice that allows additionally growing up THz resonator. We performed numerical analyze of the structure based on the relaxation time approximation of electron transport in superlattice and wave line description for matching between antenna and superlattice. We choose the superlattice parameters, which are technically available today and show that the detector responsivity can be enhanced several hundred times in comparison to well known existent variants of a such detector, also the frequency selection quality can achieve a very high value (F/-F/spl sim/10/sup 3/).","PeriodicalId":408575,"journal":{"name":"Proceedings of the 2nd IEEE Conference on Nanotechnology","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2002-11-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130707114","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}
