1. A non-volatile composite nanotube switch, comprising:

  • a first conductive terminal;

    a composite nanotube article comprising a first plurality of nanotubes and a second plurality of nanoscopic particles, the first plurality and the second plurality selected according to a predefined ratio, at least a portion of the composite nanotube article in electrical contact with the first conductive terminal, wherein the ratio of the first plurality and the second plurality is between 1 and 10;

    a second conductive terminal in contact with at least a portion of the composite nanotube article, wherein the composite nanotube article is physically and electrically interposed between the first and second conductive terminals; and

    control circuitry in electrical communication with and configured to apply electrical stimulus to the first and second conductive terminals.
