In-Sn-Zn-O thin film transistors (ITZO-TFTs) have attracted increasing attention because they show high μFE. Here, we systematically investigated the origins of the high μFE of ITZO-TFTs by thermopower modulation. The lighter m* (~0.11 m0) and longer τ (~3.6 fs) than IGZO are the origins of the high μFE of ITZO-TFTs.
