A reversible thermoelectric converter includes first and second quantum well diodes and an electrical connection between the first and second quantum well diodes without a thermal barrier between them. Each quantum well diode includes first and second electrodes wherein electrons are quantized in discrete energy levels and a dielectric layer providing a potential barrier between the first and second electrodes. When electrons in the first quantum well diode have a higher temperature than the electrons in the second quantum well diode, electric voltage fluctuations resulting from transitions of the electrons between the energy levels in the first quantum well diode are coupled from the first quantum well diode to the second quantum well diode. The reversible thermoelectric converter can be operated for power conversion of thermal energy to electric energy, as a heat pump or a refrigerator, or as an amplifier. A planar array of reversible thermoelectric converter elements provides a desired output voltage and current.

Reversible thermoelectric converter

A method of depositing micron-sized metal lines on a dielectric substrate, such as polyimide. The dielectric is covered with a thin metallic layer, of a first metal placed in a reaction cell containing a gas-phase molecular species containing a second metal, and exposed to a focused laser beam. A translation stage moves the dielectric relative to the beam to selectively deposit micron-sized second metal lines on the metallic layer. The metallic layer on the unirradiated portion of the substrate is subsequently etched away, leaving the lines adhered to the dielectric surface.
