摘要： A memristive routing device includes a memristive matrix, mobile dopants moving with the memristive matrix in response to programming electrical fields and remaining stable within the memristive matrix in the absence of the programming electrical fields; and at least three electrodes surrounding the memristive matrix. A method for tuning electrical circuits with a memristive device includes measuring a circuit characteristic and applying a programming voltage to the memristive device which causes motion of dopants within the memristive device to alter the circuit characteristic. A method for increasing a switching speed of a memristive device includes drawing dopants from two geometrically separated locations into close proximity to form two conductive regions and then switching the memristive device to a conductive state by applying a programming voltage which rapidly merges the two conductive regions to form a conductive pathway between a source electrode and a drain electrode.

摘要： A method of making a crystalline semiconductor structure provides a photonic device by employing low thermal budget annealing process. The method includes annealing a non-single crystal semiconductor film formed on a substrate to form a polycrystalline layer that includes a transition region adjacent to a surface of the film and a relatively thicker columnar region between the transition region and the substrate. The transition region includes small grains with random grain boundaries. The columnar region includes relatively larger columnar grains with substantially parallel grain boundaries that are substantially perpendicular to the substrate. The method further includes etching the surface to expose the columnar region having an irregular serrated surface.
