Linear I-V for bare silver nanowire suggests metallic behavior but high tunnel resistance indicates presence of insulating layer on the surface. Identical I-Vs obtained for isolated gold nanoparticle and heterostructure suggests that electron transport across nanowires in the latter is governed by gold nanoparticles in contrast to expected ballistic or diffusive transport along their length.(c) 2006 American Institute of Physics.</p>1 aSharma, J.1 aVivek, J., P.1 aVijayamohanan, K., P.1 aSingh, P.1 aDharmadhikari, C., V.  uhttps://library.ncl.res.in/content/directed-organization-gold-nanoclusters-silver-nanowires-step-forward-heterostructure-102313nas a2200205   4500008004100000022001400041245010000055210006900155260010300224300001400327490000600341520148900347653002301836653003101859653001401890100001801904700001801922700003601940856013101976       2006                        eng d  a1533-488000aElectron transfer behavior of monolayer protected nanoclusters and nanowires of silver and gold0 aElectron transfer behavior of monolayer protected nanoclusters a  a25650 NORTH LEWIS WAY, STEVENSON RANCH, CA 91381-1439 USAbGwangju Jeonnam Nano Technol UnioncNOV  a3464-34690 v63 a<p>Understanding the electron transfer behavior of nanometer sized, both metallic and semiconducting particles and wires is important due to the fundamental interest in size and shape dependent electronic properties and also because of its applications in nano-electronic devices like single electron transistors and molecular switches. Monolayer protected nanoclusters enable one simple and elegant method of synthesis of these types of metallic and semiconducting materials using interfacial chemistry as has been successfully used in several applications ranging from catalysis to molecular electronics. The success of this type of nanostructured materials is due in part to the well known protecting/stabilizing action of the ligands (also known as surface passivating/capping agents), which facilitate the synthesis and processing of these hydrophobic colloids in solution form. The present article discusses the electron transfer behavior of silver nanowires and nanoparticles with varied sizes. In particular, we have investigated the electrochemical properties of silver nanowires (diameter 70 nm, length several micrometers) and compared with the behavior of similar relatively larger sized nanoparticles (size 40 nm). A critical analysis of the redox behavior of silver nanowires and nanoparticles is presented in aqueous medium under various electrolytic conditions along with a comparison of analogous properties of smaller sized (2-7 nm) silver and gold nanoclusters.</p>10acyclic voltammetry10ananoclusters/nanoparticles10aNanowires1 aSharma, Jadab1 aVivek, J., P.1 aVijayamohanan, Kunjukrishna, P.  uhttps://library.ncl.res.in/content/electron-transfer-behavior-monolayer-protected-nanoclusters-and-nanowires-silver-and-gold-002272nas a2200253   4500008004100000022001400041245007000055210006900125260009200194300001000286490000600296520136500302653002101667653003001688653004101718100002301759700001901782700002201801700001801823700002101841700003001862700002201892856010401914       2009                        eng d  a1947-293500aSynthesis of Sb-doped SnO2 nanowires and hyperbranched structures0 aSynthesis of Sbdoped SnO2 nanowires and hyperbranched structures  a26650 THE OLD RD, STE 208, VALENCIA, CA 91381-0751 USAbAMER SCIENTIFIC PUBLISHERScAPR  a38-430 v13 a<p>Branched nanostructures of semiconducting materials are of great interest for their potential applications in optoelectronic, photonic devices and sensors. We herein describe a facile single-step chemical vapor deposition route for the synthesis of Sb-SnO2 hyperbranched nanostructures comprised of elongated nanowires with 30-40 nm diameter and 10-20 Am length. The morphology and structure has been characterized by scanning electron microscopy (SEM), transmission electron microscopy (TEM), selective area electron diffraction (SAED), and powder X-ray diffraction (XRD). Also, a possible mechanism is proposed for the growth of nanowires into the hyperbranched form on the basis of the substrate effect, the role of Au nanoparticles, and the effect of Sb doping on specific morphology evolution. Interestingly, electrical conductivity measurements as a function of temperature suggest a semiconducting behavior, despite being governed by different electron-transport mechanisms with activation energies of 0.55 and 0.17 eV, which correspond to pure SnO2 and Sb-SnO2 nanowires, respectively. A precise control over the operating parameters not only envisages custom-designed, branched structures by a simple and economical route but also offers an alternative method to the expensive and tedious nanofabrication techniques for industrial applications.</p>10aAu Nanoparticles10achemical vapor deposition10aSb-SnO2 Hyperbranched Nanostructures1 aSathe, Bhaskar, R.1 aPatil, Mrudula1 aWalke, Pravin, S.1 aVivek, J., P.1 aLele, Ashish, K.1 aPillai, Vijayamohanan, K.1 aMulla, Imtiaz, S.  uhttps://library.ncl.res.in/content/synthesis-sb-doped-sno2-nanowires-and-hyperbranched-structures-0
