Electrochemical Transistor Based on Tungsten Oxide with Optoelectronic Properties

Abstract : This paper reports the integration of an electrochromic inorganic oxide semiconductor (WO3) into an electrolyte gated transistor device. The resulting electrochromic transistor (EC-T) is a novel optoelectronic device, exhibiting simultaneous optical and electrical modulation. These devices show an On-Off ratio of $$ 5\times 10^{ 6} $$5×106 and a transconductance (gm) of 3.59 mS, for gate voltages (VG) between −2 and 2 V, which, to the authors knowledge, are one of the best values ever reported for this type of electrochemical transistors. The simple and low-cost processing together with the electrical/optical performances, well supported into a comprehensive analysis of device physics, opens doors for a wide range of new applications in display technologies, biosensors, fuel cells or electrochemical logic circuits.
