Electrostatic charge model for dual-layer oxide thin-film transistors

A simple electrostatic two-equation model for dual-layer thin-film transistor (TFT) operation is developed. The model distributes electrostatic charge between the top and bottom semiconductor layers, and the resulting transfer and mobility curves accurately simulate experimental...

Shallow Trap States Control Electrical Performance of Amorphous Oxide Semiconductor Thin‐Film Transistors

ABSTRACT The performance of n ‐type amorphous oxide semiconductor thin‐film transistors (TFTs) is controlled by the electronic states near the conduction band mobility edge. Here, the full subgap density of states (DoS) of amorphous InGaZnO (a‐IGZO) TFTs, used in display panels a...
