Influence of antimony doping on structure and conductivity of tin oxide whiskers

Tin dioxide whiskers doped with different concentrations of antimony (0–0.25 at.%) have been grown from SnO and Sb2O3 mixture in a tube furnace in a flowing mixture of argon and oxygen at a constant source temperature. The whiskers possess high structural perfection. Influence of Sb on crystal structure, morphology and conductivity of SnO2 whiskers is investigated. Antimony doping allows a decrease in the resistance of SnO2 whiskers up to 106 times.
