  • Sensing device for incorporating thermally bistable material
    Patent number: 5574281
    Abstract: A device capable of storing information, comprising a new sulfide alloy embedded in a substrate, the alloy exhibiting a metal-semiconductor phase transition with hysteresis as a function of temperature and a positive temperature coefficient. In one embodiment of the device the bistable material may be represented by the formula Ba(Co.sub.1-x Ni.sub.x)S.sub.2-y, wherein x is between 0 and 1 and y varies from 0-2.
    Type: Grant
    Filed: November 14, 1994
    Date of Patent: November 12, 1996
    Assignee: University of Iowa Research Foundation
    Inventors: Lee S. Martinson, John W. Schweitzer, Norman C. Baenziger
  • Method of making sulfide alloys exhibiting thermal bistability
