摘要: A nanoscale switching device (400) comprises a first electrode (102) of a nanoscale width; a second electrode (108) of a nanoscale width; an active region (106) disposed between the first and second electrodes, the active region containing a switching material; an area (402) within the active region 5 that constrains current flow between the first electrode and the second electrode to a central portion of the active region; and an interlayer dielectric layer (110) formed of a dielectric material and disposed between the first and second electrodes outside the active region. A nanoscale crossbar array (900) and method of forming the nanoscale switching device are also disclosed.

摘要: A memristor (100, 100', 100") based on mixed-metal-valence compounds comprises: a first electrode (115); a second electrode (120); a layer (105) of a mixed-metal-valence phase in physical contact with at least one layer (110, 110a, 110b) 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 (125). One of the first and second electrodes is in electrical contact with either the layer of the mixed-metal-valence phase or a layer (110a) of a fully oxidized phase and the other is in electrical contact with the layer (or other layer (110b)) 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 (100') and an ON-switched diode (100") are also provided. A method of operating the memristor is further provided.
