In addition, this category of materials possesses a number of unique properties different from bulk materials, such as excellent flexibility, high surface-to-volume ratio, etc., which make them attractive for applications in flexible electronics, sensors, and so on. Nevertheless, controlled and uniform assembly of synthetic 1-D materials with high scalability is still one of the major bottleneck challenges towards the materials and device integration for circuit applications. Here we illustrate the large-scale heterogeneous assembly of highly ordered arrays of organic and inorganic 1-D materials via electrospinning and contact printing methods. These innovative approaches enable the control of the ordering and packing density of 1-D nanomaterials in a significant degree, thus are versatile for the design and implementation of novel electronic circuitry. In particular, we have configured assembled inorganic 1-D materials as a variety of functional electronic and optoelectronic devices, including field-effect transistors, Schottky diodes and photodiodes on both rigid and flexible substrates. Furthermore, we have fabricated and characterized an all-nanowire integrated image sensor. This demonstrates that these functional components can be heterogeneously integrated together to implement nanomaterial-based circuitry.","PeriodicalId":380183,"journal":{"name":"2010 International SoC Design Conference","volume":"34 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116812222","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 paper presents a low energy consumption RNG including a serial-to-parallel shift register, a 32-bit register and a pseudo random number generator (PRNG) module. The design can be implemented completely in digital circuit and requires no external components. A prototype was implemented using Chartered Semiconductor 0.18 μm CMOS technology and the power consumption was less than 5 mW. The random sequence produced by the proposed architecture has good statistical properties based on National Institute of Standards and Technology (NIST) statistical test.
