Abstract
A thin film transistor disposed on a substrate is provided. The TFT includes a gate layer, an insulation layer, a carrier transmission layer, a passivation layer, a first source/drain layer, and a second source/drain layer. The gate layer is disposed on the substrate. The insulation layer is disposed on the gate layer. The carrier transmission layer is disposed on the insulation layer. The carrier transmission layer includes an active layer and a mobility enhancement layer. The passivation layer is disposed on the active layer. The first source/drain layer is disposed on the active layer. The second source/drain layer is disposed on the active layer. The mobility enhancement layer includes a first element. The active layer includes a second element. The electronegativity of the first element is smaller than that of the second element to enhance the carrier mobility of the active layer.
