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.

Abstract: A method for increasing adhesion between a substrate and a polymeric imprintable material during an imprinting procedure. The method includes chemically bonding a plurality of molecules to a surface of a substrate to form a self-assembled monolayer thereon. A monomer is copolymerized with the self-assembled monolayer to form a polymeric imprintable material that is chemically bonded to the self-assembled monolayer. Adhesion between the polymeric imprintable material and the substrate is substantially increased by the self-assembled monolayer.
