Abstract

Antimony (Sb) doping of SnO 2 nanowires (NWs) was investigated for its optical and electrical effects. The low-temperature photoluminescence spectra of SnO 2 NWs varied significantly with increasing Sb content, where the temperature-dependence of the visible emission at ca. 400 nm was distinctive with Sb-doping, indicating different defect states, such as neutral and positively charged oxygen vacancies. Field effect transistors (FETs) with low-level Sb-doped SnO 2 NW channels exhibited higher mobility, charge concentration, and faster response and recovery to UV light than intrinsic SnO 2 NW FETs.
