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) Population and lifetime of excited states of shallow impurities in Ge Type Journal Article
Year 1979 Publication Sov. Phys. JETP Abbreviated Journal Sov. Phys. JETP
Volume 49 Issue 2 Pages 355-362
Keywords Ge, photothermal ionization, shallow impurities
Abstract An investigation was made of the dependences of the intensities of photothermal ionization lines of excited states of shallow impurities in Ge on the intensity of impurity-absorbed background radiation and on temperature. The results obtained were used to find the density and lifetime of carriers of lower excited states of the impurity centers. The lifetimes of the excited states of donors in Ge were 10-~-10-" sec and the lifetime of the lower excited state of acceptors was -lo-' sec. In the presence of background radiation the population of the excited states was very different from the equilibrium value and, in particular, a population inversion of the 2pk, state relative to the 3p0 and 3s states was observed.
