摘要:
A nanoscale switching device is constructed such that an electroforming process is not needed to condition the device for normal switching operations. The switching device has an active region disposed between two electrodes. The active region has at least one switching layer formed of a switching material capable of transporting dopants under an electric field, and at least one conductive layer formed of a dopant source material containing dopants that can drift into the switching layer under an electric field. The switching layer has a thickness about 6 nm or less.
摘要:
An apparatus and related methods for modulating an electromagnetic radiation beam are described. A composite material is positioned in the path of the radiation beam, the composite material comprising a plurality of commonly oriented metallic first lines spaced apart by less than a wavelength of the radiation beam and a plurality of commonly oriented metallic second lines also spaced apart by less than that wavelength. The second lines are positioned in a crossing arrangement with the first lines, a crosspoint location being defined where each first line crosses each second line. An electrically programmable impedance memory element is positioned at each crosspoint location and is electrically coupled between the first and second lines corresponding to that crosspoint location, each impedance memory element having an electrically programmed state. The composite material modulates the radiation beam according to the electrically programmed states of the impedance memory elements.
摘要:
Apparatus and systems are provided for data signaling between a centralized transceiver and a plurality of sensor nodes. Each sensor node independently generates electrical power from one or more renewable sources. Each sensor node transmits data corresponding to sensed physical variables to the transceiver by free-space signaling. Large areas can be monitored by a vast array of such sensors without the need for wiring, optical fibers or other tangible interconnections.

An optoelectronic memory cell has a transparent top electrode, a photoactive layer, a latching layer, and a bottom electrode. The photoactive layer absorbs photons transmitted through the top electrode and generates charge carriers. During light exposure, the latching layer changes its resistance under an applied electric field in response to the generation of charge carriers in the photoactive layer.

A memcapacitor device (100) includes a first electrode (104) and a second electrode (106) and a memcapacitive matrix (102) interposed between the first electrode (104) and the second electrode (106). Mobile dopants (111) are contained within the memcapacitive matrix (102) and are repositioned within the memcapacitive matrix (102) by the application of a programming voltage (126) across the first electrode (104) and second electrode (106) to alter the capacitance of the memcapacitor (100). A method for utilizing a memcapacitive device (100) includes applying a programming voltage (126) across a memcapacitive matrix (102) such that mobile ions (111) contained within a memcapacitive matrix (102) are redistributed and alter a capacitance of the memcapacitive device (100), then removing the programming voltage (126) and applying a reading voltage to sense the capacitance of the memcapacitive device (100).
