【 摘 要 】
References(18)The impact of electroforming polarity on solid Pt/TiO2/Pt memristor is studied. We observe the negative electroforming leads to small and concentrated forming voltages; while positive electroforming leads to the relatively larger and dispersed forming voltages. These phenomena are interpreted by employing a modified bipolar percolation model. We argue the distribution of polarity-related forming voltage is attributed to the different filament growth patterns under the different electroforming polarities. This work facilitates understanding the electroforming procedure and then benefits fabrication for reliable devices with controllable electroforming behaviour.
