A substrate bias effect on the stability of a-Si:H TFT fabricated on a flexible metal substrate

Abstract

Hydrogenated amorphous silicon thin film transistors were fabricated on a flexible metal substrate. A negative voltage at a floated gate can be induced by a negative substrate bias through a capacitor between the substrate and gate electrode. This can recover the shifted-threshold voltage to an original value.
