Transparent ZnO thin-film transistor fabricated by rf magnetron sputtering
TLDR
In this paper, the authors fabricated ZnO thin-film transistors by rf magnetron sputtering on Si substrates held near room temperature, and the best devices had field effect mobility of more than 2 cm2/V and an on/off ratio>106.Abstract:
We fabricated ZnO thin-film transistors by rf magnetron sputtering on Si substrates held near room temperature. The best devices had field-effect mobility of more than 2 cm2/V s and an on/off ratio>106. These ZnO films had resistivity ∼105 ohm cm, with high optical transparency (>80% for wavelength >400 nm), and compressive stress <0.5 GPa. The combination of transparency in the visible, excellent transistor characteristics, and low-temperature processing makes ZnO thin-film transistors attractive for flexible electronics on temperature sensitive substrates.read more
