  Title High speed hot-electron superconducting bolometer Type (up) Conference Article
  Year 1993 Publication Proc. SPIE Abbreviated Journal Proc. SPIE  
  Volume 2104 Issue Pages 181-182  
  Keywords NbN HEb, Nb, Al  
  Abstract Physical limitation of response time of a superconducting bolometer as well as the nature of non-equilibrium detection of radiation have been investigated for Al, Nb and NbN thin films in spectral range from submillimeter to near-infraredwavelengths [1,2]. In the case of ideal heat removal from the film with the f_‘. 100A thickness the detection mechanism is an electron heating effect that is not selective to radiation wavelength in a very broad range. The response time ofan electron heating bolometer is determined by an electron-phonon interaction time. This time is of about 10 ns, 0.5 ns and 20 ps for Al, Nb, and NbN correspondingly near the critical temperature of the superconducting film. Thesensitive area of the bolometer consists of a number of narrow strips (with awidth of 1µm) connected in parallel to contact pads; these pads together witha sapphire substrate and a ground plate represent the microstrip transmissionline with an impedance of 50 Q.

  Title Electron-phonon interaction in thin YBaCuO films and fast detectors Type (up) Conference Article
  Year 1993 Publication Phonon Scattering in Condensed Matter VII. Springer Series in Solid-State Sciences Abbreviated Journal Phonon Scattering in Condensed Matter VII. Springer Series in Solid-State Sciences  
  Volume 112 Issue Pages 184-185  
  Keywords YBCO HTS detectors  
  Abstract The thin. YBaCuO film response to laser and submillimeter radiation demonstrates the picosecond nonequilibrium peak on the nanosecond bolometric background. Experimental data give an evidence for the spectral dependence of picosecond photoresponse probably due to a poor efficiency of electron multiplication processes. Presented results prove an availability of fast YBaCuO thin film detector.

  Title Temperature dependence of bolometric and non-bolometric photoresponse of a structured YBa2Cu3O7-δ thin film Type (up) Conference Article
  Year 1993 Publication Phonon Scattering in Condensed Matter VII. Springer Series in Solid-State Sciences Abbreviated Journal Phonon Scattering in Condensed Matter VII. Springer Series in Solid-State Sciences  
  Volume 112 Issue Pages 193-195  
  Keywords YBCO HTS detectors  
  Abstract We investigated the temperature dependence of the transient voltage photoresponse of a current biased structured YBa2Cu3O7−δ thin film in its transition temperature region, around 79 K. Both, picosecond nonbolometric and nanosecond bolometric response to ultrashort far-infrared laser pulses were found for frequencies between 25 cm−1 and 215 cm−1. We will discuss optimum conditions for radiation detection and present an analysis of the dynamical behaviour of excited high T c thin films.

  Title Thermal boundary resistance at YBaCuO film-substrate interface Type (up) Conference Article
  Year 1993 Publication Phonon Scattering in Condensed Matter VII. Springer Series in Solid-State Sciences Abbreviated Journal Phonon Scattering in Condensed Matter VII. Springer Series in Solid-State Sciences  
  Volume 112 Issue Pages 405-406  
  Keywords YBCO films  
  Abstract The nanosecond voltage response of YBaCuo films on Al2O3, MgO and ZrO2 substrates to electromagnetic radiation of millimeter and visible ranges has been investigated. The analysis of experimental conditions for Al2O3 and MgO substrates shows that the resistance change is monitored by the Kapitza boundary shift of temperature during the temporal interval ~ 100 ns limited by the time of phonon return from a substrate into a film. The observed exponential voltage decay is described by the phonon escape time which is proportional to the film thickness and is weakly temperature dependent.

  Title Picosecond response of YBaCuO films to electromagnetic radiation Type (up) 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.
