a Circuit schematic for bilayer vOECT-based “AND/NOR” reconfigurable logic gate functions. A truth table for both states of the logic gate depending on the VGS definitions of “0” and “1”. Both devices have a W = 100 µm and the applied VDS is 0.1 V. b Input voltages (green for VIN2 and gray for VIN1) and output current (purple) for the “AND” state of the logic gate. c Input voltages and output current for the “NOR” state of the logic gate functions. d Circuit schematic for bilayer vOECT-based “OR/NAND” reconfigurable logic gate. A truth table for both states of the logic gate depending on the VGS definition of “0” and “1”. Both devices have a W = 100 µm and the applied VDS is 0.1 V. e Input voltages and output current for the “OR” state of the logic gate. f Input voltages and output current for the “NAND” state of the logic gate.
