Abstract

Ta doped SnO₂ (TTO) films prepared on quartz glass substrates at 200°C were annealed in the air to investigate the annealing effect on the structural, the optical, and the electrical properties. It is shown that the annealing for TTO films resulted in beneficial effect on the electrical resistivity by improving the carrier density and Hall mobility. The lowest resistivity was 1.4 × 10^-3 Ω cm obtained at 400°C annealing temperature. The scattering mechanism in TTO films was discussed from the optical and electrical perspectives. The variation in Hall mobility with increasing the annealing temperature may be attributed to the scattering from the ionized and neutral impurities in TTO films.
