Zusammenfassung
The Josephson photoresponse of a current biased granular Tl2Ba2CaCu2O8 thin film has been measured at 4.2 K for radiation frequencies ω in the range 20–111 cm-1. The resulting photosignal s depends nonlinearly on the incident power P satisfying the relationship s=K(ω)Pα(ω), where K is a frequency-dependent constant. The value of α increases monotonically from 0.5 at 20.2 cm-1 to 0.9 at 111 cm-1. ...
