The size relationship to actual properties is an interesting variable, with even crystal orientation being a variable. Everyone is learning novel properties of “traditional” materials while they are also creating “novel” materials. With a time of many years required to determine a materials impact on people and/or the environment, newly developed materials provide an interesting opportunity. “Do we wait for years to determine if the material is dangerous, or do we work to produce the magic bullet to cure cancer?” This is not an easy decision. If we proceed, how do we ensure safety? This paper provides insight on how we can proceed to address these issues.","PeriodicalId":219771,"journal":{"name":"2011 11th IEEE International Conference on Nanotechnology","volume":"184 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-09-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121206436","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 tungsten layer acts as a diamond nucleation-enhancing layer. Formation of tungsten-carbide (WC) complex increases the initial nucleation density and plays an important role in facilitating diamond growth characteristics. Microwave plasma-enhanced chemical vapor deposition is applied to synthesize diamond films in Ar diluted by methane without hydrogen additives at low temperature. NCD seeding and film formation were investigated as a function of the thickness of tungsten interfacial layer. Raman spectroscopy, SEM, AFM and TEM were applied to characterize NCD films in order to gain insight into the initial stage of NCD diamond synthesis.","PeriodicalId":219771,"journal":{"name":"2011 11th IEEE International Conference on Nanotechnology","volume":"34 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133499472","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}

Although optimal coupling of a fluorophore-exciting light source to the PC occurs with the use of collimated plane waves, PCEF surfaces are also capable of coupling light from focused sources but with a reduction in the obtainable enhancement factor. Using computer simulations and experimental measurements, we describe the interaction between the resonant bandwidth of a PCEF device surface and the optical design of the detection instrumentation that is used to provide fluorescence excitation. We show that highly collimated illumination is required for achieving the greatest PCEF enhancement factors, but at the expense of poor tolerance to non-uniformities in resonant wavelength across the PCEF surface. To overcome this limitation, we demonstrate a fixed wavelength/multiple incident angle scanning detection system that is capable of measuring every pixel in a PCEF fluorescence image under conditions that optimize resonant excitation efficiency.","PeriodicalId":219771,"journal":{"name":"2011 11th IEEE International Conference on Nanotechnology","volume":"374 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122822773","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}

Metallic interconnects such as Cu, Al, and single-layer graphene nanoribbons (GNR) may be used as conduits of spin information in spin-based circuits. Impact of size effects on the transport parameters and consequently on the circuit performance and energy dissipation of spin interconnects are exhaustively quantified. Spin interconnects are compacted against their CMOS counterparts at the 11.9nm technology node. Important insights into the physical limits and challenges of interconnects for future spin devices are identified to better guide the research in spintronics.","PeriodicalId":219771,"journal":{"name":"2011 11th IEEE International Conference on Nanotechnology","volume":"47 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"117224502","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}
