| abstract |
A thin-film transistor and a manufacturing method thereof are characterized in that: the active layer is a group IV-VI compound semiconductor film; the group IV-VI compound is one of geranium sulfide (GeS), germanium selenide (GeSe), germanium telluride (GeTe), tin selenide (SnSe), and tin telluride (SnTe) or a ternary, quaternary, or quinary compound thereof; the active layer is deposited by sputtering; and thermal annealing is performed after the active layer is deposited. The thin-film transistor has high carrier mobility and a high current on/off ratio and therefore meets the needs of high-resolution display development. |
