Dynamic Response Characteristics of a Novel Electrolyte Transistor

Novel organic transistors utilizing acid/alkaline chemistry have been investigated for their unique device chemistry and customizability. The research presented here shows a multiphysics model for a polymerelectrolyte transistor (PET) simulated in COMSOL Multiphysics. Dynamic transient response and current-voltage characteristics are determined from multiple simulations of an alkaline-acid-alkaline PET in common collector configuration, showing transistor activity in the ionic currents of the device. This shows that increases to the emitter voltage, while holding all other parameters constant, leads to increased ionic currents in the base-collector channel. Similar results are found for varying the base voltage while holding all other parameters constant. These results show that through modification of the electrolyte composition of the device, customized transistor responses are obtained, which leads to custom logic built in to the device chemistry.
