Low-temperature transport properties of individual SnO2 nanowires

Gas-flow assisted bulk synthesis of V-type SnO2 nanowires

“…Consequently, the SnO 2 nanostructures are of very high purity. As compared with the previous results [5][6][7][8][9][10][11][12], the growth of V-, W-and Z-type NWs, in the present work, does not require the specific morphology and size of the Sn-containing precursor and the assistance of any other materials. It is relatively a simple method to prepare V-type SnO 2 NWs in large amount.…”

“…It is therefore of significant importance to prepare such nanostructured materials in large amount for the further fabrication of much complex and functional nanostructures. Recently, Wang et al [5] reported that the heating of the phen-capped Sn nanoparticles in a NaCl flux is effective to prepare the V-shaped SnO 2 nanorods with angle of 112.11, a material with large band gap (3.6 eV) having wide applications in the gas sensor, electrochemical energy conversion, field emission or photoluminescence [6][7][8][9][10][11][12]. The formation of such V-shaped nanorods is proposed to the multi-armed structure originated directly from a core of Sn nanoparticles seed, following the vapor-liquid-solid (VLS) mechanism [5].…”

Temperature dependent growth and optical properties of SnO2 nanowires and nanobelts

“…The synthesis and assembly of 1D SnO 2 nanostructures such as wires and belts have attracted great interest due to their unique applications in gas sensors and field-effect transistors (Comini et al 2002;Kolmakov et al 2005;Dattoli et al 2007). There are several methods for the synthesis of SnO 2 nanowires and belts such as chemical vapour deposition (Ma et al 2004;Calestani et al 2005), thermal evaporation Wang et al 2004;Duan et al 2005;He et al 2006) and different chemical synthesis routes (Zheng et al 2001;Her et al 2006). In this paper, we report the growth of SnO 2 nanowires and nanobelts on silicon substrates through a vapour-liquid-solid (VLS) mechanism by the evaporation of Sn powders at different temperatures.…”

Structural, optical, and electronic properties of colloidal CuO nanoparticles formed by using a colloid-thermal synthesis process

“…The prospect of potential applications of CuO nanostructures has led to substantial research and development efforts to form various types of nanostructures [9,10]. Among these CuO nanostructures, the formation of CuO nanowires and nanoparticles has been extensively studied by using several techniques, such as precursors [11], hydrothermal decomposition [12], self-catalytic growth [13], and solvothermal [14] routes.…”
