CA 2073955

The disclosed substance has a composition of a general chemical formula of Bi2-(Sr2Ca1)1=xt(La2Y1)x-Cu y-Oz, where 0.4~x~1, y=2 and z=9-10.5, wherein said substance is an insulator or a semiconductor in the dark, and has a photoconductivity Q(.lambda.,T) in conjugate with superconductivity of a superconductor of an adjacent component of the Bi-SrCa-LaY-Cu-O system at a critical temperature (T) of less than 105-115 K and less than 65-85 K at photoexcitation in an optical wavelength range (.lambda.) of 420-670 nm. The present invention relates to a method for producing the same and a superconductive optoelectronic device with the same. The present invention also relates to an element, a device and an apparatus in superconductive optoelectronics.

Divulgation concernant une substance avec une composition de formule chimique générale Bi2-(Sr2Ca1)1=xt(La2Y1)x-Cu y-Oz, où 0,4~x~1, y=2 et z=9-10,5; ladite substance est un isolant ou un semi-conducteur à l'obscurité, et a une photoconductivité Q(lambda,T) conjuguée avec la supraconductivité d'un supraconducteur correspondant à un composé voisin du système Bi-SrCa-LaY-Cu-O à une température critique (T) inférieure à 105-115 degrés K, et inférieure à 65-85 degrés K à l'état de photoexcitation dans une plage de longueur d'onde optique (lambda) de 420-670 nm. La présente invention porte sur une méthode pour produire cette substance et sur un dispositif supraconducteur optoélectronique qui l'utilise. La présente invention porte enfin sur un élément, un dispositif et un appareil pour optoélectronique à supraconducteur.
