Abstract Electrical behaviors of anatase TiO2 nanoparticles were investigated at high pressure. Resistive switching effect was observed at different pressures and enhanced with pressure. The I-V characteristic curves show stable resistive switching performance as a function of pressure and also indicate that the optimal properties appear below 21.4 GPa. The larger current at high pressure was obtained, which should be ascribed to the semiconductor-metallic transformation. The conductive mechanism was discussed and high pressure phase transitions play a key role in resistive switching behaviors.
