摘要：
We have developed amorphous zirconium-indium-zinc-oxide (ZrInZnO) as the channel layer to fabricate thin film transistors through a solution process. The best ZrInZnO transistor exhibited a field effect mobility of 3.80 cm2/Vs, an onoff ratio of similar to 107, a threshold voltage of 0.44 V and a subthreshold swing of 0.42 V/dec. The function of the Zr element was investigated through electrical and thin-film characterization. We found that Zr atoms behaved as effective carrier suppressors and the presence of Zr elements inhibited the crystallization of the InZnO phase. ((c) 2012 WILEY-VCH Verlag GmbH & Co. KGaA, Weinheim)
