A stable, high-mobility ZnO thin-film semiconductor was fabricated by thermal treatment of a
solution-deposited thin film from a solution of Zn (OAc) 2/2-ethanolamine in methoxyethanol.
This ZnO thin-film semiconductor was composed of closely packed ZnO single crystals (∼
30 to 50 nm) having a hexagonal structure assuming a preferred orientation with its c-axis
perpendicular to the substrate. Field-effect mobility of 5− 6 cm2 V-1 s-1 and current on-to-off
ratio of 105− 106 were demonstrated with this ZnO thin-film semiconductor in thin-film …
