Research output: Patent


Methods and apparatus for storing information or energy. An array of nano vacuum tubes is evacuated to a pressure below 10−6 Torr, where each nano vacuum tube has an anodic electrode, a cathodic electrode spaced apart from the anodic electrode, and an intervening evacuated region. An excess of electrons is stored on the cathodic electrode.
