Tail state mediated conduction in zinc tin oxide thinfilm phototransistors under below bandgap optical excitation
Abstract We report on the appearance of a strong persistent photoconductivity (PPC) and conductor-like behaviour in zinc tin oxide (ZTO) thinfilm phototransistors. The active ZTO channel layer was prepared by remote plasma reactive sputtering and possesses an amorphous structure. Under sub-bandgap e...
