This three finite squared holes array constitutes an individual micro-cell, respectively. The measured transmission peak wavelength reveals that the surface plasmons are Fabry-Perot type resonance to different integer order. The ratio of periodicity between the super-periodic structure p and the NtimesN micro-cell d determines the integer order (where N is number of isolated hole; N=3, 4 and 5). Namely, when p/d>4, the order 4 and 5 surface plasmon modes with average hole spacing p/4 and p/5 are observed in 4times4 micro-cell array, respectively. The transmission intensities of order 4 mode are the strongest, and those of order 5 modes are barely seen. But as p/d approaches 5, the order 4 mode gradually disappear with the emergence of order 5 mode. The 3times3 and 5times5 micro-cell array have the same result. These phenomena suggest that the surface plasmons are Fabry-Perot type resonance within a super unit cell. The dispersion relations of surface plasmons are also observed.","PeriodicalId":6415,"journal":{"name":"2007 7th IEEE Conference on Nanotechnology (IEEE NANO)","volume":"19 1","pages":"279-282"},"PeriodicalIF":0.0,"publicationDate":"2007-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"73503896","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}

This new mathematical model correctly assumes that carbon nanotubes form a line shape after undergoing AC dielectrophoretic force (DEP) compare to existing model that assumes carbon nanotubes to be a spherical particle. The new mathematical model is based on a new developed model for applied torque due to dielectrophoresis. It is also a method for controlled assembly of the CNTs on microstructures that have the plausibility to be scaled to wafer-level manufacturing. Simulation results are presented for the developed models. The developed model can be used to detect the position of carbon nanotubes and further implemented in the separation of semiconducting and metallic band structure carbon nanotubes. Ultimately, the developed model will provide a critical and major step towards the use of carbon nanotubes in the manufacturing of electronics and sensors for potential use in electrical circuits, as fiber and film, computer circuits, light bulb filament, ultracapacitors, combat jackets, etc.","PeriodicalId":6415,"journal":{"name":"2007 7th IEEE Conference on Nanotechnology (IEEE NANO)","volume":"34 1","pages":"383-386"},"PeriodicalIF":0.0,"publicationDate":"2007-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"73514532","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}

TM polarization occurs in a length of mere 4.9 mum and it has a great potential to be integrated in a complex photonic integrated circuits. To our knowledge, this is the first ever demonstration of silicon-based TM polarizer in telecommunication wavelength. 2D and 3D finite difference time domain (FDTD) simulation was utilized to design a triangular array of air holes in silicon. Such photonic crystal TM polarizer was fabricated in silicon-on-insulator wafer using focused ion beam and reactive ion etch with air hole diameter of 170 nm and pitch distance of 347 nm for the TM polarizer and 371 nm for the input and output waveguide. The device was fully characterized using tunable lasers in the wavelength range of 1,528 nm ~ 1,604 nm. Transmitted light intensities of the TE and TM polarized lights were measured which clearly showed the TE polarized light is filtered out around 1.55 mum wavelength.","PeriodicalId":6415,"journal":{"name":"2007 7th IEEE Conference on Nanotechnology (IEEE NANO)","volume":"31 1","pages":"1093-1096"},"PeriodicalIF":0.0,"publicationDate":"2007-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"76671615","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}

CNT was found to be sensitive under near IR radiation and it could be used as IR sensing element. Parylene C thin film was used as a conformal pin hole free insulating layer and oxygen barrier for protecting CNTs during the detection. The IR transmission properties of parylene C layer and the influence on the response of the CNT sensor were studied. Our experimental results showed that the CNT sensor without parylene C protection exhibited current change when it was exposed to the IR laser. The sensing current percentage changes decreased when the parylene C thin film substrate was placed between the CNT sensor and IR laser source. It implied the IR absorption behavior of parylene C thin film. We also found that the IR absorption level is proportional to the thickness of the parylene C layer. The parylene C packaged CNT sensor was fabricated and tested under near IR radiation. Preliminary results indicated that the CNT IR detector coated with parylene C was capable of sensing IR radiation and exhibited repeatable response. Moreover, the IV characteristic of the sensor chip was measured when it was surrounded by dry ice for long time to investigate its long term stability under moisture environment. Therefore, the packaging process can become possible to fabricate a CNT based IR sensor array which possesses more stable and reliable performance.","PeriodicalId":6415,"journal":{"name":"2007 7th IEEE Conference on Nanotechnology (IEEE NANO)","volume":"8 1","pages":"778-781"},"PeriodicalIF":0.0,"publicationDate":"2007-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"74258178","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}

Their photocatalytic property is evaluated by the photodegradation of brilliant red dye under visible light irradiation. For comparison, Cu2O nanocubes are synthesized and evaluated with photocatalytic property as well. The results show that the photocatalytic activity of the Cu2O nanorods is more than one time higher than that for Cu2O nanocubes under visible light. Additionally, the structure of the Cu2O nanorods is very stable and they can not be oxidized to CuO even during the photocatalytic reaction process. It is noticeable that this kind of Cu2O nanorods has remarkable large surface areas 47.6 m2/g, which is about forty times as large as that for as-prepared Cu2O nanocubes and it is also three times larger than that for the reported porous Cu2O nanoparticles. The large surface area of Cu2O nanorods leads to its higher adsorption ability to the brilliant red dye and excellent high photocatalytic activity under visible light. Since Cu2O nanorods are very stable and have high photocatalytic activity under visible light, they are expected to be used in photocatalytic oxidation technology practically in the future.","PeriodicalId":6415,"journal":{"name":"2007 7th IEEE Conference on Nanotechnology (IEEE NANO)","volume":"24 1","pages":"975-978"},"PeriodicalIF":0.0,"publicationDate":"2007-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"74082749","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}
