Abstract

Zinc tin oxide (ZTO) based thin-film transistors (TFTs) were fabricated on glass substrate by using sol-gel method. The fabricated ZTO TFT had bottom gate and top contact structure with ZTO layer formed by spin coating from ZTO solution. The fabricated TFT showed field-effect mobility of about 2 - $4\;cm^2/V{\cdot}s$ with on/off current ratios >$10^7$, and threshold voltage of 2 V.
