Growth, Characterization And I-V characteristics Of Tin Oxide Nanowires

“…After obtaining the super saturation, the nanostructures start growing outwards. This confirms the Vapor-Liquid-Solid (VLS) growth [13] of the SnO 2 nanowires. The impurities such as C and Cu in EDX spectra are due to Cu grids and carbon film on Cu grids.…”

“…Thermal evaporation technique seems to be the most popular process due to its simplicity, low-cost infrastructure and high throughput. 1 D tin oxide may be formed in the form of tubes [13], belts [14], rods, wires [15] and sheet, and these structures with high aspect ratio (i.e., size confinement in two coordinates) offer better crystallinity, higher integration density, and lower power consumption. Motivated by applications of tin oxide nanostructures, numerous efforts have been made to control the size and shape of SnO 2 nanostructures.…”

Localized growth and in situ integration of nanowires for device applications

“…14,15 The aforementioned procedures overcome the limitations to grow inorganic coatings compatible with CMOS techniques, but the formed device configuration is less desirable in terms of thick interface layers, 16 interference between growth and characterization circuits 17 or the formation of polycrystalline tube structures. 18 Such issues have significant influence on the performance of devices for applications such as gas sensors.…”

“…Similarities to the procedure presented herein are based on a templated growth of inorganic structures using pre-grown carbon nanotubes on micro-hotplates leading to polycrystalline tin oxide nanotubes. 18 However, our approach simplifies the integration of such very versatile highly crystalline nanowire structures by using a generic one-step growthintegration process that employs the heating element, both for the nanowire growth and for the high temperature operation of a gas sensing device. The heater with the as-grown nanowires is used to supply the required energy for effective adsorptiondesorption processes of gaseous molecules and therefore facilitating sensor operation conditions.…”

Ultrafast and scalable laser liquid synthesis of tin oxide nanotubes and its application in lithium ion batteries

“…Tin oxide (SnO 2 ) nanotubes, as a promising anode material for lithium ion batteries, 7-10 can be synthesized via either chemical or physical approaches. [11][12][13][14][15][16][17][18] However, the dimension control, purity and scalability are still issues yet to be addressed. Precision nanomanufacturing of tin oxide nanotubes would therefore be a crucial step towards their energy applications.…”
