A photoconductive substances of the type of bismuth - strontium - calcium - lanthanum - yttrium - copper - oxygen

摘要

The disclosed substance has a composition of a general chemical formula of MATH 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.
