Abstract

We report on the observation of reversible and immediate resistance switching by high-k oxide Ta₂O₅/organic parylene-C hybrid dielectric-gated VO₂ thin films. Resistance change ratios at various temperatures in the insulating regime were demonstrated to occur in the vicinity of phase transition temperature. We also found an asymmetric hole-electron carrier modulation related to the suppression of phase transition temperature. The results in this research provide a possibility for clarifying the origin of metal-insulator transition in VO₂ through the electrostatic field-induced transport modulation.
