ABSTRACT:
The disclosed superconductive optoelectronic device with the basic substance Bi.sub.2 O.sub.3 or Bi.sub.2 O.sub.3 ;M.sup.2+ (M=Ca,Sr,Cu) of superconductive-conjugate photoconductivity has a substrate, a photoconductive gate region formed on the substrate, and a source region and a drain region formed on the substrate at opposite sides of the gate region so as to face toward each other across the gate region. The source region and the drain region are made of a Bi-based superconductive material. The gate region is made of such the basic material Bi.sub.2 O.sub.3 or Bi.sub.2 O.sub.3 ;M.sup.2+ (M=Ca,Sr,Cu) of superconductive-conjugate photoconductivity, which reveals photoconductivity at a temperature below the transition temperature of the above relevant Bi-based superconductive material. Also disclosed are superconductive optoelectronic devices formed of an organized integration of the above superconductive optoelectronic devices to develop effectively a new field of "Superconductive Optoelectronics".
