Abstract
Tin-doped indium oxide (ITO) thin films were deposited at room temperature by a dual-oxygen-ion-beam-assisted evaporator system and the effects of doped tin concentrations in the films on the electrical properties of the ITO films were investigated. Doped tin atoms in amorphous ITO films caused extra scattering and structural defects due to the inactivation of tin atoms in the films. Therefore, increasing the tin concentration decreased the conductivity. The lowest resistivity of indium oxide (IO) and ITO obtained was 3.6 × 10-4 Ω-cm for IO and 4 × 10-4 -7 × 10-4 Ω-cm for 5-25 wt% SnO2. The mobility and mean free path of these films were 20-63 cm2/V·s and 3.3-7.4 nm, respectively.
