This study introduces a simple and cost effective strategy for the synthesis of vertical arrays of silicon nanowires and ZnO nanostructures (nanorod and multipod structures). Formation of vertical nanostructured arrays is confirmed by SEM and HRTEM imaging as well as XRD and Raman measurements. We have investigated field emission properties of the as-synthesized vertical nanostructured arrays. Our results show that these SiNWs-ZnO nanostructures are highly efficient and stable field emitters.</p>1 aDevarapalli, Rami, Reddy1 aShinde, Deodatta, R.1 aBarka-Bouaifel, Fatiha1 aYenchalwar, Sandeep, G.1 aBoukherroub, Rabah1 aMore, Mahendra, A.1 aShalke, Manjusha, V.  uhttps://library.ncl.res.in/content/vertical-arrays-sinws-zno-nanostructures-high-performance-electron-field-emitters-001242nas a2200169   4500008004100000022001400041245010000055210006900155260011000224300001600334490000700350520051300357100002800870700003300898700002500931856011600956       2014                        eng d  a1463-907600aEnhanced photoluminescence and photoactivity of plasmon sensitized nSiNWs/TiO2 heterostructures0 aEnhanced photoluminescence and photoactivity of plasmon sensitiz  aTHOMAS GRAHAM HOUSE, SCIENCE PARK, MILTON RD, CAMBRIDGE CB4 0WF, CAMBS, ENGLANDbROYAL SOC CHEMISTRYcSEP  a17786-177910 v163 a<p>A light sensitive wide band gap radial heterojunction between TiO2 and nSiNWs sensitized by gold nanoparticles is reported.

We prepared rGO with two self-assembled monolayers (SAMs), one linear and the other with aromatic triazoles through a click cycloaddition reaction. A fivefold photocurrent enhancement was observed for triazole linkers over the aminopropyltrimethoxysilane (APTMS) linker. Cyclic voltammetry (CV) and impedance measurements also suggest fast electron transfer on account of the low resistance offered by the click-modified rGO surface whereby introduction of triazoles offers the efficient bridge between the donor AuNPs and acceptor rGO.</p>10aGold10agraphene10aNanoparticles10aphotophysics10asurface plasmon resonance1 aYenchalwar, Sandeep, G.1 aDevarapalli, Rami, Reddy1 aDeshmukh, Ashvini, B.1 aShelke, Manjusha, V.  uhttps://library.ncl.res.in/content/plasmon-enhanced-photocurrent-generation-click-chemically-modified-graphene-001526nas a2200181   4500008004100000245005200041210005100093260000800144300002800152490000800180520095500188100002801143700002401171700002301195700002401218700001901242856008301261       2017                        eng d00aOptical antenna effect on SiNWs/CuS photodiodes0 aOptical antenna effect on SiNWsCuS photodiodes  cMAY  aArticle Number: 16006350 v2143 aOne-dimensional architectures between silicon nanowires (SiNWs) and CuS were fabricated by radio-frequency (RF) magnetron sputtering and analyzed for solid-state photodetector application. Inspired by the subwavelength optical concentration by the surface plasmons on metal nanostructures at the nanoscale, we investigated the effect of gold nanorods (AuNRs) on the optical absorption and photodetection properties of the heterojunction photodiode. AuNRs acting as an optical trapping antenna enhances the light absorption, consequently boosting the photocurrent from the device. A maximum photoresponsivity of 0.36 mA W-1 was achieved under 665 nm excitation wavelength independent of the bias, a value similar to 13 times higher than for the heterojunction photodiode without AuNRs. Such plasmonic sensitization can be useful for improving the sensitivity of visible as well as IR photodetectors. (C) 2017 WILEY-VCH Verlag GmbH & Co.
