Title (up) Picosecond response of YBaCuO films to electromagnetic radiation Type Conference Article
Year 1990 Publication Proc. European Conf. High-Tc Thin Films and Single Crystals Abbreviated Journal Proc. European Conf. High-Tc Thin Films and Single Crystals
Volume Issue Pages 457-462
Keywords YBCO HTS detectors
Abstract Radiation-induced change of the resistance was studied in the resistive state of YBaCuO films. Electron-phonon relaxation time T h was determmed from direct ep measurements and analysis of quasistationary electron heating. Temperature dependence of That TS 40 K was found to – ep be T h.. T'. The resul ts show that ep detectors with the response time of few picosecond at nitrogen temperature can be realized.

Title (up) Picosecond YBa2Cu3O7−δdetector for far‐infrared radiation Type Journal Article
Year 1992 Publication J. Appl. Phys. Abbreviated Journal J. Appl. Phys.
Volume 72 Issue 11 Pages 5496-5499
Keywords YBCO HTS detectors
Abstract We report on a picosecond YBa2Cu3O7−δ detector for far‐infrared radiation. The detector, consisting of a current carrying structure cooled to liquid‐nitrogen temperature, was studied by use of ultrashort laser pulses from an optically pumped far‐infrared laser in the frequency range from 25 to 215 cm−1. We found that the sensitivity (1 mV/W) was almost constant in this frequency range. We estimated a noise equivalent power of less than 5×10−7 W Hz−1/2. Taking into account the results of a mixing experiment (in the frequency range from 4 to 30 cm−1) we suggest that the response time of the detector was few picoseconds.

Title (up) Processes of electron-phonon interaction in thin YBaCuO films Type Journal Article
Year 1991 Publication Phys. C: Supercond. Abbreviated Journal Phys. C: Supercond.
Volume 185-189 Issue Pages 1371-1372
Keywords YBCO HTS detectors
Abstract The ultrafast voltage response of YBaCuO films to laser radiation is studied and compared with previously investigated quasiparicles response to radiation of submillimeter wavelength range. Voltage shift under the visible light radiation has two components. Picosecond response realized as suppression superconductivity by nonequilibrium excess quasiparticles, response time is determined by quasiparticles recombination rate. Nanosecond response is probably due to bolometric effect.

Title (up) Subnanosecond photoresponse of a YBaCuO thin film to infrared and visible radiation by quasiparticle induced suppression of superconductivity Type Journal Article
Year 1992 Publication Appl. Phys. Lett. Abbreviated Journal Appl. Phys. Lett.
Volume 60 Issue 7 Pages 903-905
Keywords YBCO HTS detectors
Abstract We observed subnanosecond photoresponse of a structured superconducting YBa2Cu3O7−δ thin film to infrared and visible radiation. We measured the voltage response of a current biased film (thickness 700 Å) in a resistive state to radiation pulses. From our results we conclude a response time of about 90 ps and a responsivity of about 4×1010 Ω/J. We attribute the response to Cooper pair breaking and suppression of the superconducting energy gap induced by nonequilibrium quasiparticles.
