Positive gate bias stress-induced hump-effect in elevated-metal metal–oxide thin film transistors Project supported by the Science and Technology Program of Suzhou City, China (Grant No. SYG201538) and the National Natural Science Foundation of China (Grant No. 61574096). |
(color online) Time evolutions of transfer characteristics under PBS with values of Vg stress of (a) 20 V, (b) 25 V, (c) 30 V at 20 °C. The TFTs have geometry W/L = 100/12 μm. (d) Voltage shift of VH versus gate bias stress. |
