▎ 摘 要
NOVELTY - The superconducting transition-edge thermal sensor, comprises a superconducting film defining an active area for incidence of quanta there, in that superconducting film is made of a superconductor exhibiting a charge carrier density below 1013 cm-2 and an electronic heat capacity below 103 kb at the critical temperature of superconductor. The superconductor is formed by two layers of two-dimensional crystals stacked on top of another. Two electrodes (E1,E2) are provided and shaped to form an antenna for allowing or improving electromagnetic coupling between the active area and electromagnetic radiation. The active region is embedded in a ring resonator, Fabry-Perot cavity, photonic crystal cavity or other type of optical cavity, for optical coupling with electromagnetic radiation. USE - Superconducting transition-edge thermal sensor. ADVANTAGE - A sharp active area transition is highly desirable, to achieve an optimum detection performance as it enables to generate detectable voltage pulses even from weak photon-induced heat pulses. DESCRIPTION OF DRAWING(S) - The drawing shows a schematic representation of a sensor for which the superconductor is formed by two layers of graphene twisted by an angle of 1.1 degree.
