FIELD EFFECT TRANSISTOR, DISPLAY ELEMENT, IMAGE DISPLAY DEVICE, AND SYSTEM |
摘要 |
<p>A disclosed field effect transistor includes a gate electrode to which a gate voltage is applied, a source electrode and a drain electrode for acquiring a current in response to the gate voltage, an active layer provided adjacent to the source electrode and the drain electrode, the active layer being formed of an n-type oxide semiconductor, and a gate insulator layer provided between the gate electrode and the active layer. In the field effect transistor, the n-type oxide semiconductor is formed of an n-type doped compound having a chemical composition of a crystal phase obtained by introducing at least one of a trivalent cation, a tetravalent cation, a pentavalent cation and a hexavalent cation.</p> |
