Tailoring these novel properties to their maximum potential requires precise control of the atomic layer growth process. In recent years, catalytic growth of 2-D nanomaterials using chemical vapor deposition (CVD) process has emerged as an attractive approach due to their low-cost, scalability, and ability to transfer the grown materials on various substrates. In this approach, the morphology and purity of the catalytic surface plays a critical role on the shape, size, and growth kintectics of the 2D nanomaterial. In this work, we present the results of our systematic studies of the role of catalytic surface morphology on the shape and domain size of CVD grown hexagonal (h)-BN films. The present work clearly demonstrates that the presence of surface roghness in the form of ridges leads to a preferential growth of small-domain triangular BN sheets. A 100-fold reduction in the surface roughness leads to increased domain BN triangles, eventually transitioning to large-domain hexagonal shaped BN sheets.","PeriodicalId":367660,"journal":{"name":"14th IEEE International Conference on Nanotechnology","volume":"50 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116982899","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 key novelty of the proposed nanoscale technology is (1) the introduction of nano-substrate such as polymer (plastic), paper, glass, metal, or other tissue/fabric and (2) the imprinting processes. Nano-substrate consists of the pixelated nano-structures that are specially designed to display red, green and blue primary colors, and infrared radiation, and can be pre-fabricated on any substrate. The imprinting process activates the pixels according to the desired image that is transferred onto nano-substrate. The effective optical intensity of the pixelated nano-structures is tuned by an intensity control layer (ICL), which is patterned according to the desired color image and covert information. Using this technology, any given full-color image and/or covert data can be embedded on a prefabricated nano-substrate. This new technology makes possible to practically and efficiently use the nano-structures as a visual information display (next generation of holography) and as an high density and long term optical storage medium. In this paper, the concept, the design of the nano-media and the proof-of-concept experimental work are presented. We successfully produced full-color images with 1,270 pixels per inch (PPI) resolution using various ICLs on the fabricated nano-substrate. We also embedded covert information into the nano-media by patterning the intensity of infrared sub-pixels and successfully read the information using an infrared camera device. The texts, QR codes and photos were all tested as the covert information which was retrieved without any loss. The color images and stored data are of very high quality that can be controlled by the imprinting processes.","PeriodicalId":367660,"journal":{"name":"14th IEEE International Conference on Nanotechnology","volume":"28 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127521695","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}

Electrical breakdown has been known as the way to fundamentally understand the electrical properties of nanotubes and an approach to develop MWNT based transistors and sensors. Normally, electrical breakdown was known to be happened in the center of MWNT because of the thermal accumulation. However, considering the effect of thermal dissipation, the electrical breakdown could be mechanically controlled by an additional heat sink, which could be the substrate of MWNT device. Therefore, the electrical breakdown process is controllable through controlling Joule heating and thermal dissipation. In this research, we study the crucial factors that affect the electrical breakdown. The AFM based nano robot is used to measure the conductance distribution, and manipulate the three dimensional structure of MWNT in order to change the position of heat sink to control the location where electrical breakdown happened. The controllable electrical breakdown is an alternative approach for conducting bandgap engineering in nanodevice and fabricating high performance nano sensors and transistors.","PeriodicalId":367660,"journal":{"name":"14th IEEE International Conference on Nanotechnology","volume":"77 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125376934","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 using the graphene as collector/emitter in a bipolar transistor (BJT) and not as a channel material, there is relaxation of the tolerances in graphene thickness and quality, simplifying growth, device design and fabrication. This also enables the exploitation of engineered defects in thicker (2-5ML) graphene films for flexible electronics, currently not being considered, as well controlled uniform defects are preferred to localized random defect clusters. We will discuss an SiF4 based growth method that enables temperature programmed defect engineering. We will discuss the use of electron-beam induced current (EBIC) to characterize these materials. Based on recent results at our lab, a graphene/SiC Schottky junction behaves as a collector (GC) and an emitter (GE) in a BJT with common emitter gain, β>50, measured under phototransistor operation mode. The transparent graphene Schottky collector/emitter junction enables opto-electronic applications, minimizes series resistance in the device due to the thin graphene layer, and also minimizes charge storage time (diffusion capacitance), enabling high speed operation. Furthermore, the observation of β>50 with a GE-BJT demonstrates that significant minority carrier injection occurs in these Schottky junctions, contrary to what is commonly assumed. The injection of minority carriers has the ability to induce conductivity modulation in the underlying semiconductor, reducing overall device resistance. The role of minority carriers in Schottky Junctions will be discussed.","PeriodicalId":367660,"journal":{"name":"14th IEEE International Conference on Nanotechnology","volume":"26 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116595267","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}
