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) Plots of −ΔVH versus stress time in log–log scales under PBS at different temperatures. The degradations of −ΔVH follows the time-dependent power-law with the exponent n ranging from about 0.83 to 1.03. |
