Nowadays, optical antennas are attracting a lot of attention due to their enormous potential for applications in nanoscale optical microscopy, spectroscopy, solar energy conversion, integrated optical nano-circuitry, and molecular sensing, etc.[1]. This increased focus is due to the progress in nano-manufacturing technologies, which makes it possible to utilize sub-wavelength plasmonic structures in different shapes and sizes [2]. Different shapes of the apertures are evaluated for bio-sensing and in the infrared domain such as H-shape, cross shape as well as quad-triangles [3], and bowtie [4]. One fabrication process that can be very helpful in the fabrication of nano-antennas at a small scale (nm and $mu mathrm{m}$ scale) is utilizing nano-probe technologies for forming nano-Schottky based tunneling diode rectifiers [5].","PeriodicalId":6742,"journal":{"name":"2021 IEEE 16th Nanotechnology Materials and Devices Conference (NMDC)","volume":"21 1","pages":"1-5"},"PeriodicalIF":0.0,"publicationDate":"2021-12-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"82129524","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}

A polymer nanocomposite can be prepared at temperatures below the HTS cable delamination temperature, mitigating this issue. The proposed polymer nanocomposite was composed of polymethyl methacrylate (PMMA) and impregnated with silicon dioxide (SiO2) to improve the dielectric performance of the base polymer. Dielectric breakdown testing shows a significant increase in the dielectric strength of PMMA/SiO2 composites at cryogenic temperatures when compared to room temperature testing. The increase is most significant across higher filler concentrations where the dielectric strength more than triples over room temperature values from 60–90 kV/mm to ~290 kV/mm. The impact a colder testing environment has on dielectric performance makes PMMA/SiO2 nanocomposites a promising low temperature processing dielectric for adoption into HTS cable systems.","PeriodicalId":6742,"journal":{"name":"2021 IEEE 16th Nanotechnology Materials and Devices Conference (NMDC)","volume":"10 1","pages":"1-4"},"PeriodicalIF":0.0,"publicationDate":"2021-12-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"82467588","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 bilayer sensor was developed for measuring strains at levels much higher than the conventional metallic foil-based strain gauges; while achieving higher gauge factor, lower hysteresis and improved linearity comparing to other current advanced flexible strain sensors. Such improved piezoresistive responses originate from reproducible opening and closing of the uniformly distributed, high density microcracks that were generated in the carbon nanotube thin film during controlled pre-stretch training. The constraining of microcrack opening-and-closing and nanotube rotation help to stabilize and mitigate large strains and significant resistance variation, leading to superior mechano-electric performances.","PeriodicalId":6742,"journal":{"name":"2021 IEEE 16th Nanotechnology Materials and Devices Conference (NMDC)","volume":"146 1","pages":"1-4"},"PeriodicalIF":0.0,"publicationDate":"2021-12-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"77027312","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}

However, achieving a measurable second order nonlinear signal in thin films and two dimensional materials has relied on using pulsed lasers and intense optical focusing, which limits potential applications require nonlinear response by using low laser power or from nanoscale materials. Here we achieved second harmonic generation from nanoflakes of two dimensional materials with lateral size smaller than the diffraction limit by using a double nanohole plasmonic optical tweezer with a low-power continuous-wave laser. The plasmonic double nanohole aperture enhances the local field intensity and allows for single nanoflake trapping and significant second harmonic generation at the nanoscale. The two dimensional property of nanoflakes allows for positioning in an area with high local field intensity and achieving higher nonlinear response than bulk nonlinear nanoparticlesWe observed an increase in second harmonic generation power two orders of magnitude higher than. other bulk materials such as lithium niobate nanoparticles. This allows for having strong nonlinear generation at the nanoscale for applications such as subwavelength nonlinear imaging or information processing.","PeriodicalId":6742,"journal":{"name":"2021 IEEE 16th Nanotechnology Materials and Devices Conference (NMDC)","volume":"32 1","pages":"1-4"},"PeriodicalIF":0.0,"publicationDate":"2021-12-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"73833561","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}

Green's function methods were used to calculate quantum transmission and single molecule conductance in both the low temperature (coherent) and room temperature (decoherent) regimes. Several approaches were attempted for modeling the energy levels of the heme-sites, including semi-empirical methods, and quantum transmission was calculated at several different length scales. This result was compared to experimental findings as well as other modeling results for similar cytochrome structures, such as electron hopping models applied to neighboring heme sites. The results show that coordinated hemes prefer a low spin state with electron delocalization over the porphyrin rings and coordinating histidine groups from the protein scaffold. Orbital overlap between heme centers was shown to have a significant impact on quantum transport, with perpendicular heme centers having a rate limiting effect on transport. Semi-empirical models such as the extended Hückel method were found to be inaccurate for modeling transport, showing the importance of electron-electron repulsion and a more detailed model for the organometallic bonding.","PeriodicalId":6742,"journal":{"name":"2021 IEEE 16th Nanotechnology Materials and Devices Conference (NMDC)","volume":"40 1","pages":"1-5"},"PeriodicalIF":0.0,"publicationDate":"2021-12-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"73249435","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}
