英文摘要	"negative" electric-pulse-induced reversible resistance (epir) switching phenomenon was found in in/pcmo/pt sandwich, in which the high resistance can be written with positive voltage pulses, and the low resistance can be reset using negative voltage pulses (the positive voltage direction is defined as going from the top electrode to the bottom electrode). this is just the opposite from the "positive" epir effect in ag/pcmo/pt sandwich, in which the high resistance can be written only with negative voltage pulses, and the low resistance can be reset using positive voltage pulses. the i-v hysteresis curves of in/pcmo/pt and ag/pcmo/pt sandwiches also show opposite directions, i.e., counterclockwise and clockwise under a negative voltage region for indium and ag electrode systems, respectively. c-v characteristics show that the barrier does not exist in ag/pcmo/pt sandwich, while in/pcmo/pt sandwich exhibits an obvious schottky-like barrier. we suggest that in the negative epir behavior in in/pcmo/pt structure, the resistance states are mainly controlled changing the schottky-like barrier at the interface with the weak effect of carrier trapping process, while the positive epir behavior in ag/pcmo/pt sandwich mainly depends on the carrier trapping process at the interface.
