<p>A thermotunneling converter is disclosed comprising a pair of electrodes (6, 8) having inner surfaces substantially facing one another, and a spacer (7) or plurality of spacers positioned between the two electrodes (6, 8), having a height substantially equal to the distance between the electrodes, and having a total cross-sectional area that is less than the cross-sectional area of either of the electrodes. In a preferred embodiment, a vacuum is introduced, and in a particularly preferred embodiment, gold that has been exposed to cesium vapor is used as one or both of the electrodes (6, 8).</p> |
