Fig. 5From: Voltage-Polarity Dependent Programming Behaviors of Amorphous In–Ga–Zn–O Thin-Film Transistor Memory with an Atomic-Layer-Deposited ZnO Charge Trapping LayerThe threshold voltage shifts of the a-IGZO TFT memory devices with different processed ZnO charge trapping layers as a function of a positive programming voltage for constant programming time of 80 ms and b negative programming voltage for constant programming time of 1 μs. For each condition, five devices were measured.Back to article page
