Size‐Dependent Photoconductance in SnO₂ Nanowires

Abstract

Tin oxide (SnO2) nanowires of different diameters can be conveniently grown by combining the chemical influence of a single‐molecular precursor [Sn(OtBu)4] with vapor–liquid–solid growth. Upon illumination with UV light at a wavelength of 370 nm, the nanowires exhibit interesting photoconductance, which can be modulated by tuning the wire diameter, as demonstrated for samples possessing radial dimensions in the range 50–1000 nm (see image).

All-Inorganic Perovskite CsPb2Br5 Microsheets for Photodetector Application

“…And, the faster response speed of this CsPb 2 Br 5 thin microsheets based photodetector could be ascribed to the high crystal quality of asprepared CsPb 2 Br 5 microsheets, which guaranteeing the efficient optical absorption and photogeneration of carriers. On the other side, the short transit time and large surface-to-volume ratio of CsPb 2 Br 5 thin microsheets tend to induce defects and dangling bonds on the surface of microsheets [40,41]. The switching in the two states exhibited faster photoresponse characteristics, allowing the device to act as a high-quality photosensitive switch.…”

Copper (II) oxide nanowires for p-type conductometric NH3 sensing

“…Morphology of the nanowires was observed using a Zeiss (Auriga) scanning electron microscope (SEM) equipped with an Oxford X-ray energy dispersive spectrometer for EDS analysis. Monocrystalline SnO 2 nanowires were synthesized by chemical vapor deposition (CVD) following a process described elsewhere [18].…”

Nanofabrication of Metal Oxide Patterns Using Self-Assembled Monolayers

“…106 and so on. Various kinds of tin oxide nano-structures such as nano-fibers 107 , nano-wires 108,109 , nano-belts 110 , nano-tubes 111 , nano-rods 112,113 , spirals, nano-rings 114 , zigzag nano-belts 115 , grains 116 , flakes 116 , plates 116 , meshes 117 and columnar thin films 118 were reported. Surface coating of substrates with tin oxide nano-structures are strongly required for the future devices.…”
