Abstract

The family of AM4Q8 chalcogenide Mott insulators gained attention in recent years for its application opportunities. Here, we explore and validate the resistive switching mechanism of thin-film of GaV4S8 sandwiched between TiN electrodes. The device is fabricated via processes and materials compatible with microelectronics standards and demonstrates a good control and endurance of the non-volatile transitions over a large range of resistance. The achieved multi-level property enables to envision application as Resistive Random Access Memories (RRAM) or neuromorphic applications. We also showed the important role of the current compliance in the control of the transitions.
