Abstract
A thermionic or thermotunneling gap diode device consisting of two silicon electrodes maintained at a desired distance from one another by means of spacers. These spacers are formed by oxidizing one electrode, protecting certain oxidized areas and removing the remainder of the oxidized layer. The protected oxidized areas remain as spacers. These spacers have the effect of maintaining the electrodes at a desired distance without the need for active elements, thus greatly reducing costs.
