N2 - We report the modulation of electrical properties of charge-ordered YbFe2O4 films using electrostatic carrier doping. By utilizing the current switching effect under a high DC electric field as a probe, we detected the charge-ordered phase in the c-axis-oriented YbFe2O4 films grown by pulsed-laser deposition. A three-terminal electric double-layer device with a thin channel of YbFe2O4 and an ionic liquid (IL) gate dielectric showed reversible modulation of channel conductance under a positive gate voltage. Furthermore, we demonstrated that conductance modulation could be enhanced by customizing the molecular structure of the IL.
