Abstract: A memristive device includes: a first electrode; a second electrode; a memristive matrix interposed between the first electrode and the second electrode; a porous dopant diffusion element in physical contact with the memristive matrix and in proximity to the first electrode and the second electrode; and a first mobile dopant species which moves through the porous dopant diffusion element in response to a programming electrical field. A method for using a memristive device having a porous dopant diffusion element includes applying a voltage bias to generate a programming electrical field such that dopants move through the porous dopant diffusion element, thereby changing the distribution of dopants within a memristive matrix to form a first state; removing the voltage bias, the dopants being substantially immobile in the absence of the programming electrical field; and applying a reading energy to the memristive device to sense the first state.

Abstract: A switching device includes at least one bottom electrode and at least one top electrode. The top electrode crosses the bottom electrode at a non-zero angle, thereby forming a junction. A metal oxide layer is established on at least one of the bottom electrode or the top electrode. A molecular layer including a monolayer of organic molecules and a source of water molecules is established in the junction. Upon introduction of a forward bias, the molecular layer facilitates a redox reaction between the electrodes, thereby reducing a tunneling gap between the electrodes.
