The electrical properties, such as carrier density and mobility, can be further tuned by the thickness of In2O3 and ZnO layers beyond material composition.

Therefore, an enhanced <inline-formula> <tex-math>$mu _{text {FE}}$ </tex-math></inline-formula> is achieved together with high on/off ratio and steep subthreshold slope (SS). Besides, devices with channel length down to 80 nm are fabricated, with CF4 plasma treatment utilized to suppress carrier density, achieving high on-current, steep SS and enhancement-mode operation.
