Abstract
A memristor based on mixed-metal-valence compounds comprises: a first electrode; a second electrode; a layer of a mixed-metal-valence phase in physical contact with at least one layer of a fully oxidized phase. The mixed-metal-valence phase is essentially a condensed phase of dopants for the fully oxidized phase that drift into and out of the fully oxidized phase in response to an applied electric field. One of the first and second electrodes is in electrical contact with either the layer of the mixed-metal-valence phase or a layer of a fully oxidized phase and the other is in electrical contact with the layer (or other layer) of the fully oxidized phase. The memristor is prepared by forming in either order the layer of the mixed-metal-valence phase and the layer of the fully oxidized phase, one on the other. A reversible diode and an ON-switched diode are also provided. A method of operating the memristor is further provided.
