Broadband THz detection by high-Tc Josephson junctions

Detection of THz radiation by YBa 2 Cu 3 O 7-x Josephson bicrystal junctions with high characteristic voltages I c R n up to 8 mV has been studied. The high-resistance junctions have demonstrated a classical detection of radiation with frequencies up to terahertz range. It was shown by numerical sim...

Description
Summary:Detection of THz radiation by YBa 2 Cu 3 O 7-x Josephson bicrystal junctions with high characteristic voltages I c R n up to 8 mV has been studied. The high-resistance junctions have demonstrated a classical detection of radiation with frequencies up to terahertz range. It was shown by numerical simulations, that the values of noise equivalent power NEP < 5 times10 -15 W/Hz 1/2 can be reached at the frequencies up to 1.5 THz at junction temperature of 30 K.
