    摘要: A memristor has a first electrode, a second electrode parallel to the first electrode, and a switching layer disposing between the first and second electrodes. The switching layer contains a conduction channel and a reservoir zone. The conduction channel has a Fermi glass material with a variable concentration of mobile ions. The reservoir zone is laterally disposed relative to the conduction channel, and functions as a source/sink of mobile ions for the conduction channel. In the switching operation, under the cooperative driving force of both electric field and thermal effects, the mobile ions are moved into or out of the laterally disposed reservoir zone to vary the concentration of the mobile ions in the conduction channel to change the conductivity of the Fermi glass material.

    摘要: A nanoscale switching device has an active region disposed between two electrodes of nanoscale widths. The active region contains a switching material that carries mobile ionic dopants capable of being transported over the active region under an electric field to change a resistive state of the device. The switching material further carries immobile ionic dopants for inhibiting clustering of the mobile ionic dopants caused by switching cycles of the device. The immobile ionic dopants have a charge opposite in polarity to the charge of the mobile ionic dopants, and are less mobile under the electric field than the mobile ion dopants.

    摘要: An asymmetric switching rectifier includes a first switching device to allow electric current to flow while in a first state and inhibit electric current in a second state and a second switching device connected in a head-to-head formation to said first switching device, said second switching to allow electric current to flow while in a first state and inhibit electric current in a second state. A first electric current to turn said switching devices to said first state is different than a second electric current to turn said switching devices to said second state. The rectifier further includes a bypass segment to draw a bypass electric current from a center electrode between said first switching device and said second switching device.
