Resistance switching in a SiC nanowire/Au nanoparticle network

Resistance switching in a semiconductor nanowire/metal nanoparticle system is demonstrated. SiC nanowires grown on a Si substrate and decorated with Au nanoparticles are measured using W microprobes in a scanning electron microscope, where one probe is grounded and the other is biased. HIGH and LOW states can be toggled by applying a negative or positive pulse voltage. The switching mechanism is attributed to a charge transfer between the SiC nanowires and the Au nanoparticles.
