From: Diffusive Memristive Switching on the Nanoscale, from Individual Nanoparticles towards Scalable Nanocomposite Devices

Figure 2

Diffusive memristive switching is observed by AFM measurements on an individual AgPt nanoparticle using a conductive tip. In a single hysteresis loop (a) the device shows a SET (switching towards LRS) and RESET (switching towards HRS) event for both, positive and negative polarity. For the reliable determination of the respective switching voltages, the current threshold of 5 nA is selected for a SET and 0.5 nA for a RESET. The comparison of 70 consecutive hysteresis loops (b) implies a certain distribution of the respective switching voltages. The individual hysteresis cycles are colour coded (first cycles: red colour, last cycles: blue colour).
