Study of Two-dimensional Electrochemical Sensor using an Inorganic Semiconductor

Abstract

We have been studied the light addressable amperometric sensor (LAAS) using an organic device since it has advantages in cost, flexibility, and large sensing area. However, it can be expected that the LAAS device using an inorganic semiconductor has high-durability even under severe conditions. We will demonstrate the array of amperometric sensors with discrete electrodes on Schottky junctions or pn junctions of Si wafer.
