Abstract
We report on the fabrication of ZnO-based depletion-load-type inverter composed of two n -channel ZnO thin-film transistors (TFTs) with a low- k poly-4-vinylphenol and high- k poly(vinylidene fluoride-trifluoroethylene) double polymer dielectric. One of the two ZnO channels in the inverter was illuminated by 352 nm wavelength ultraviolet so that the illuminated ZnO channel might be depleted. That ZnO-TFT plays as a driver transistor in the inverter set where the original TFT is used as a load one. The both TFTs show the same mobility of ∼0.3 cm2 /V s and our inverter operates with a voltage gain of ∼4 at low supplied voltages (5-7 V), demonstrating a dynamic response of ∼20 ms.
