Abstract
A thin film transistor is disclosed comprising comprises a substrate, a dielectric layer, and a semiconductor layer. The semiconductor layer, which is crystalline zinc oxide preferentially oriented with the c-axis perpendicular to the plane of the dielectric layer or substrate, is prepared by liquid depositing a zinc oxide nanodisk composition. The thin film transistor has good mobility and on/off ratio.
