Controllable Threshold Voltage in Organic Complementary Logic Circuits with an Electron-Trapping Polymer and Photoactive Gate Dielectric Layer

“…For each voltage transfer characteristic (VTC) curve, when an input voltage ( V In ) was increased from 0 to the voltage supply V DD , the output voltage ( V Out ) decreased from V DD to 0 V, indicating an obvious inverting operation. − The voltage gain, defined as −d V Out /d V In , is summarized in Figure b. The obtained maximum gain at a certain V DD is similar to that of previous organic inverters. ,,,,,, The V M values were estimated to be 3.4, 5.0, 6.2, 7.5, and 10.3 V from a V DD of 15, 18, 20, 22, and 25 V, respectively. V M of the initial logic circuit did not appear at the theoretical point of 1 / 2 V DD because the circuit devices have differences in the V th and μ parameters of the pOTFT and nOTFT.…”
