Abstract: Some embodiments relate to a thin film transistor comprising an active layer over a substrate. An insulator is stacked with the active layer. A gate electrode structure is stacked with the insulator and includes a gate material layer having a first work function and a first interfacial layer. The first interfacial layer is directly between the insulator and the gate material layer, wherein the gate electrode structure has a second work function that is different from the first work function.
