제목 Synthesis of IGO thin film by using solution deposition method in low temperature
초록 Indium gallium oxide thin films with different annealing temperature and indium ratio were prepared on si(1000 Å) wafer by the solution deposition method. As annealing temperature increases, the mobility of TFTs increases before annealing temperature at 500 ℃. The mobility of TFTs was changed by indium ratio. The maximum value of mobility, ~19.5 cm2/v∙s, was obtained by annealing at 500 ℃. The mobility of low temperature, ~0.34 cm2/v∙s, was obtained by annealing at 300 ℃. The On-to-off current ratios were >106. The average of transmittances with different indium ratio was 98 %. The optical band gap of the films was varied with increasing gallium content from 3.83 eV to 4.70 eV.
