In this work, we investigate resistive switching properties of tin oxide (SnOx) memristors. The SnOx resistance change layer was deposited using mist chemical vapor deposition (mist CVD), which is an open-air non-vacuum process. The fabricated device exhibits stable I-V curve behavior for 500 cycles, with an ON/OFF ratio of approximately 10 and forming-free resistive switching characteristics.
Sugisaki et al. (Thu,) studied this question.
