  Title Electron–phonon interaction in disordered conductors Type Journal Article
  Year (down) 1999 Publication Phys. Rev. B Condens. Matter Abbreviated Journal Phys. Rev. B Condens. Matter  
  Volume 263-264 Issue Pages 190-192  
  Keywords disordered conductors, electron-phonon interaction  
  Abstract The electron–phonon interaction is strongly modified in conductors with a small value of the electron mean free path (impure metals, thin films). As a result, the temperature dependencies of both the inelastic electron scattering rate and resistivity differ significantly from those for pure bulk materials. Recent complex measurements have shown that modified dependencies are well described at K by the electron interaction with transverse phonons. At helium temperatures, available data are conflicting, and cannot be described by an universal model.

  Title Spectrum of thermal fluctuation noise in diffusion and phonon cooled hot-electron mixers Type Journal Article
  Year (down) 1998 Publication Applied Physics Letters Abbreviated Journal Appl. Phys. Lett.  
  Volume 72 Issue 12 Pages 1516-1518  
  Keywords HEB mixer; thermal fluctuation noise; TFN  
  Abstract A systematic study of the intermediate frequency noise bandwidth of Nb thin-film superconducting hot-electron bolometers is presented. We have measured the spectrum of the output noise as well as the conversion efficiency over a very broad intermediate frequency range (from 0.1 to 7.5 GHz) for devices varying in length from 0.08 μm to 3 μm. Local oscillator and rf signals from 8 to 40 GHz were used. For a device of a given length, the spectrum of the output noise and the conversion efficiency behave similarly for intermediate frequencies less than the gain bandwidth, in accordance with a simple thermal model for both the mixing and thermal fluctuation noise. For higher intermediate frequencies the conversion efficiency decreases; in contrast, the noise decreases but has a second contribution which dominates at higher frequency. The noise bandwidth is larger than the gain bandwidth, and the mixer noise is low, between 120 and 530 K (double side band).
