This paper discusses device models to predict the electrical characteristics of oxide semiconductor thin-film transistors (OS TFTs) with a dual-gate structure, a bilayer channel, and under positive-bias stresses. Device simulations using the appropriate device models can readily describe the operations and mechanisms of these OS TFTs.
