Surface Reactions of Two-Dimensional Materials Controlled by Field-Effect Transistors

Abstract

Electronic devices realize functions such as switches and memories by controlling the movement of electrons. On the other hand, the movement of electrons is known to govern chemical reactions. Therefore, electronic devices are expected to provide the ability to control various chemical reactions. This paper describes a method of controlling chemical reactions by voltages used in the operation of field-effect transistors, a representative electronic device. Unlike conventional electrochemical cells, this methodology can be applied to gas-phase reactions as well as liquid-phase reactions. Sample structures that do not require the application of voltage are also briefly introduced. This paper offers further possibilities for the methodology of electrical control of chemical reactions, which could be widely used by researchers in the fields of chemistry and electronics.
