A device that produces spin waves includes a base substrate, a transducer that includes a first plane defined by a first magnetic film and a second plane defined by a plurality of metal strips, and a second magnetic film having a spin-wave phase velocity lower than the first magnetic film. The second magnetic film is adjacent to the first magnetic film, and the first plane and the second plane are parallel. The plurality of metal strips are configured to receive a first signal, such that the first signal excites a first spin wave in the first magnetic film. The second magnetic film is configured to produce a second spin wave having a wavelength shorter than the first spin wave.

In a method computer storage element operation, first and second rising (or falling) clock edges are applied to first and second power inputs of the computer storage element having a transistor array between the first and second power inputs over time Twhereupon a logic value applied to an input of the transistor array is stored therein. Thereafter, first and second falling (or rising) clock edges are applied to the first and second power inputs over time T, whereupon part of an electrical charge or energy associated with the logic value stored in the transistor array is provided to circuitry that generates the first and/or second clock edge(s), wherein the value(s) of time Tand/or time Tis/are greater than a product of RC, where R is resistance associated with the computer storage element, and C is a load capacitance associated with the computer storage element.

Nanoscale thermocouples are made of a single material and are shape-engineered to contain one or more variations in their width along their length. The mono-metallic nanowire junctions resulting from the width variation(s) exploit a difference in the Seebeck coefficient that is present at these size scales. Such devices have a wide variety of uses and can be coupled with an antenna in order to serve as an infrared detector.
