SOLID STATE COOLING OR POWER GENERATING DEVICE AND METHOD OF FABRICATING THE SAME

摘要

The present invention relates to a solid state cooling/power generating device is provided comprising a first and second electrode separated by a vacuum gap. According to the present invention at least one of the electrodes is provided with a nanoscaled semiconductor heterostructure (301), which comprises at least one quantum well which in combination with the vacuum gap (315) forms a double barrier resonance structure providing conditions which allows resonant tunneling between the first and second electrode.
