Abstract
We propose a method of discriminating whether the gating effect is electrostatic or electrochemical on an electric double-layer transistor (EDLT), which can be a good guideline for examining the nature of EDLTs. The electrochemical effect between a channel and an ionic liquid depends on the gate voltage (VG). Our study on the dependence of the transport properties of a (La0.525Pr0.1Ca0.375)MnO3 (LPCMO) EDLT on VG revealed that the electrostatic effect is dominant below |VG| = 2 V, whereas the electrochemical effect is dominant at higher voltages. The modulation of the insulator-to-metal transition property of LPCMO was realized through the electrostatic effect.
