抄録

In2O3 doped with 5 wt% SnO2 (indium-tin oxide (ITO) (5 wt%)) films were deposited on glass substrates by pulsed laser deposition using an ArF excimer laser (λ= 193 nm). In all experiments, repetition rates of 150 Hz, the energy density of 6 J/cm2, and an ablation time of 30-900 sec were used. A lowest resistivity of 8.45 × 10-5 Ω ·cm and an optical transmittance of more than 80% in the visible range of the spectrum were obtained for ITO (5 wt%) films of approximately 300-nm thickness fabricated at a substrate temperature of 400°C and oxygen pressure of 10 Pa. Smooth surfaces with an average surface roughness of 1.26 nm were observed by field-emission scanning electron microscopy (FESEM) and atomic force microscopy (AFM).
