  Title Hot-electron effect in superconductors and its applications for radiation sensors Type Journal Article
  Year 2002 Publication Superconductor Science and Technology Abbreviated Journal Supercond. Sci. Technol.  
  Volume 15 Issue 4 Pages R1-R16  
  Keywords HEB, SSPD  
  Abstract The paper reviews the main aspects of nonequilibrium hot-electron phenomena in superconductors and various theoretical models developed to describe the hot-electron effect. We discuss implementation of the hot-electron avalanche mechanism in superconducting radiation sensors and present the most successful practical devices, such as terahertz mixers and direct intensity detectors, for far-infrared radiation. Our presentation also includes the novel approach to hot-electron quantum detection implemented in superconducting x-ray to optical photon counters.

  Title An ultrafast NbN hot-electron single-photon detector for electronic applications Type Journal Article
  Year 2002 Publication Supercond. Sci. Technol. Abbreviated Journal Supercond. Sci. Technol.  
  Volume 15 Issue 12 Pages 1689-1692  
  Keywords NbN SSPD, SNSPD, QE, jitter, dark counts  
  Abstract We present the latest generation of our superconducting single-photon detector (SPD), which can work from ultraviolet to mid-infrared optical radiation wavelengths. The detector combines a high speed of operation and low jitter with high quantum efficiency (QE) and very low dark count level. The technology enhancement allows us to produce ultrathin (3.5 nm thick) structures that demonstrate QE hundreds of times better, at 1.55 μm, than previous 10 nm thick SPDs. The best, 10 × 10 μm2, SPDs demonstrate QE up to 5% at 1.55 μm and up to 11% at 0.86 μm. The intrinsic detector QE, normalized to the film absorption coefficient, reaches 100% at bias currents above 0.9 Ic for photons with wavelengths shorter than 1.3 μm.

  Title 2.5 THz heterodyne receiver with NbN hot-electron-bolometer mixer Type Journal Article
  Year 2002 Publication Phys. C: Supercond. Abbreviated Journal Phys. C: Supercond.  
  Volume 372-376 Issue Pages 448-453  
  Keywords NbN HEB mixers, applications  
  Abstract We describe a 2.5 THz heterodyne receiver for applications in astronomy and atmospheric research. The receiver employs a superconducting NbN phonon-cooled hot-electron-bolometer mixer and an optically pumped far-infrared gas laser as local oscillator. 2200 K double sideband mixer noise temperature was measured at 2.5 THz across a 1 GHz intermediate frequency bandwidth centred at 1.5 GHz. The total conversion losses were 17 dB. The mixer response was linear at load temperatures smaller than 400 K. The receiver was tested in the laboratory environment by measuring the methanol line in emission. Observed pressure broadening confirms the true heterodyne detection regime of the mixer.

  Title 1.6 THz heterodyne receiver for the far infrared space telescope Type Journal Article
  Year 2002 Publication Phys. C: Supercond. Abbreviated Journal Phys. C: Supercond.  
  Volume 372-376 Issue Pages 427-431  
  Keywords NbN HEB mixers, applications  
  Abstract A low noise heterodyne receiver is being developed for the terahertz range using a phonon-cooled hot-electron bolometric mixer based on 3.5 nm thick superconducting NbN film. In the 1–2 GHz intermediate frequency band the double-sideband receiver noise temperature was 450 K at 0.6 THz, 700 K at 1.6 THz and 1100 K at 2.5 THz. In the 3–8 GHz IF band the lowest receiver noise temperature was 700 K at 0.6 THz, 1500 K at 1.6 THz and 3000 K at 2.5 THz while it increased by a factor of 3 towards 8 GHz.

  Title Electromechanical noise in a diffusive conductor Type Journal Article
  Year 2002 Publication Phys. Rev. Lett. Abbreviated Journal Phys. Rev. Lett.  
  Volume 88 Issue 22 Pages  
  Keywords  
  Abstract Electrons moving in a conductor can transfer momentum to the lattice via collisions with impurities and boundaries, giving rise to a fluctuating mechanical stress tensor. The root-mean-squared momentum transfer per scattering event in a disordered metal (of dimension L greater than the mean free path l and screening length xi) is found to be reduced below the Fermi momentum by a factor of order l/L for shear fluctuations and (xi/L)^2 for pressure fluctuations. The excitation of an elastic bending mode by the shear fluctuations is estimated to fall within current experimental sensitivity for a nanomechanical oscillator.
