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-101999nas a2200277   4500008004100000022001400041245015700055210006900212260009500281300001400376490000600390520090200396653002901298653002601327653002101353653004201374653003501416100002501451700001801476700001501494700002801509700001701537700001601554700002201570856012901592       2006                        eng d  a1533-488000aElectrochemical organization of monolayer protected gold nanoclusters on single-walled carbon nanotubes: significantly enhanced double layer capacitance0 aElectrochemical organization of monolayer protected gold nanoclu  a25650 NORTH LEWIS WAY, STEVENSON RANCH, CA 91381-1439 USAbAMER SCIENTIFIC PUBLISHERScMAY  a1387-13910 v63 a<p>This paper reports a novel electrochemical route for anchoring monolayer protected gold nanoclusters (size 8 +/- 0.2 nm) on single-walled carbon nanotube bundles, resulting in the formation of hybrid materials. Monolayer protected gold nanoclusters prepared by modified Brust synthesis route were organized on SWNT bundles by cycling-the potential in dichloromethane between -1 to +1 V at a scan rate of 50 mV/s. Monolayer protected nanoclusters in electrolyte solutions possess ionic space charge around them (double layer charging), making them suitable for organization on nanotube bundles, by tuning the electrostatic interactions. More significantly, analysis of the double layer capacitance of these hybrid materials shows almost ten times increase in capacitance compared to that of bare SWNT bundles. We believe that these hybrid materials are potentially useful in nanoelectronics.</p>10adouble layer capacitance10adouble layer charging10ahybrid materials10amonolayer protected gold nanoclusters10asingle-walled carbon nanotubes1 aMahima, Subhramanyam1 aChaki, N., K.1 aSharma, J.1 aKakade, Bhalchandra, A.1 aPasricha, R.1 aRao, A., M.1 aVijayamohanan, K.  uhttps://library.ncl.res.in/content/electrochemical-organization-monolayer-protected-gold-nanoclusters-single-walled-carbon-0
