SrTiO3 (STO) is a model switching material for valence change memristive cells; there exists general consensus that the resistive switching can be attributed to the migration of oxygen vacancies between metal electrodes and STO. However, most of STO-based devices are fabricated on Nb-doped STO substrates, which is not compatible with the current CMOS technology. Herein, by using pulsed laser deposition (PLD) technique and engineering the bottom interface through pre-annealing of the Pt electrode in O2 atmosphere, high-quality single-crystal STO films are successfully deposited on Si wafers. Moreover, destructive electroforming process is avoided, which results in volatile analog resistive switching behavior with device yield > 98%. Moreover, tunable synaptic functions, such as the short-term plasticity and the paired-pulse facilitation, are achieved in the devices.
