  • MOX multi-layer switching device comprising niobium oxide
    Patent number: 4118727
    Abstract: At least two metal oxide switch devices sandwiched together with each dev consisting of polycrystalline refractory transition metal oxide such as NbO.sub.2 formed on a conducting refractory substrate such as single crystal NbO. The polycrystalline layers on opposing outer faces of the sandwich are removed and electrical contacts made thereto. The mutually contiguous polycrystalline surfaces form an active interface where switching is adapted to take place.
