  • Growth substrate having growth nuclei made of diamonds and/or diamond-like carbon arranged on its growth surface as well as process for a uniform nucleation on the growth substrate
    Patent number: 6037240
    Abstract: A growth substrate having growth nuclei made of diamond and/or diamond-like carbon arranged on its growth surface, the orientation of over 50% of the growth nuclei deviating by less than 10.degree. from the crystal orientation defined by the growth substrate corresponding to Miller's indices (h, k, l) and the nucleus density changes between the center of the growth substrate and a distance of maximally 15 mm from the center by maximally 80%. The method also relates to a process for the growth substrate's manufacture.

  • Controllable superconductor component
    Patent number: 5721197
    Abstract: A microelectronic thin-film device having a thin superconducting layer in contact with a thin quasi-insulating conversion layer. The critical current of the superconducting layer is controlled by application of a voltage to the conversion layer by means of a gate electrode, causing the conversion layer to undergo an insulator-metal transition.
