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).
