摘要： Various embodiments of the present invention are directed to nanoscale electronic devices that provide nonvolatile memristive switching. In one aspect, a two-terminal device (600) comprises a first electrode (602), a second electrode (604), and an active region (606) disposed between the first electrode and the second electrode. The active region includes a mobile dopant (608), and a fast drift ionic species (610). The fast drift ionic species drifts into a diode-like electrode/active region interface temporarily increasing conductance across the interface when a write voltage is applied to the two-terminal device to switch the device conductance.

摘要： A method for forming three-dimensional multilayer circuit includes forming an area distributed CMOS layer configured to selectively address a set of first vias and a set of second vias. A template is then aligned with the first set of vias and lower crossbar segments are created using the template. The template is then removed, rotated, and aligned with the set of second vias. Upper crossbar segments which attach to the second set of vias are then created.

摘要： A nanoscale three-terminal switching device has a bottom electrode, a top electrode, and a side electrode, each of which may be a nanowire. The top electrode extends at an angle with respect to the bottom electrode and has an end section going over and overlapping the bottom electrode. An active region is disposed between the top electrode and bottom electrode and contains a switching material. The side electrode is disposed opposite from the top electrode and in electrical contact with the active region. A self-aligned fabrication process may be used to automatically align the formation of the top and side electrodes with respect to the bottom electrode.

摘要： In accordance with the invention, the structure (10A, 10B) of a patterned nanoscale or near nanoscale device (“nanostructure”) is repaired and/or enhanced by liquifying the patterned device in the presence of appropriate guiding conditions for a period of time and then permitting the device to solidify. Advantageous guiding conditions include adjacent spaced apart or contacting surfaces (12, 13A, 13B) to control surface structure and preserve verticality and unconstrained boundaries to permit smoothing of edge roughness. In an advantageous embodiment, a flat planar surface (12) is disposed overlying a patterned nanostructure surface (13A, 13B) and the surface (13A, 13B) is liquified by a high intensity light source to repair or enhance the nanoscale features.
