Abstract

Methods and apparatus for storing information or energy. An array of nano-capacitors is provided, where each nano-capacitor has a cathodic electrode and an anode separated by a dielectric. The thickness of the intervening solid dielectric is in the range between 0.1 nanometers and 1000 nanometers and is shorter than an electron mean free path within the dielectric. The cathodic electrode is at least 100 times larger than the thickness of the intervening dielectric in every direction transverse to the thickness of the intervening dielectric. An excess of electrons is stored on the cathodic electrode. The dielectric may be a metal oxide, particularly a native oxide of the cathode material.
