  Title Generalized diffusion equation for superconducting alloys Type Journal Article
  Year 1970 Publication Phys. Rev. Lett. Abbreviated Journal Phys. Rev. Lett.  
  Volume 25 Issue 8 Pages (up) 507  
  Keywords  
  Abstract Eilenberger's transportlike equations for a superconductor of type II can be simplified very much in the dirty limit. In this limit a diffusionlike equation is derived which is the generalization of the de Gennes-Maki theory for dirty superconductors to arbitrary values of the order parameter.

  Title Energy-loss rates for hot electrons and holes in GaAs quantum wells Type Journal Article
  Year 1985 Publication Phys. Rev. Lett. Abbreviated Journal Phys. Rev. Lett.  
  Volume 54 Issue Pages (up) 2045-2048  
  Keywords 2DEG, GaAs/AlGaAs, heat flow, electron-phonon, hole-phonon, carrier-phonon, interactions  
  Abstract We report the first direct determination of carrier-energy-loss rates in a semiconductor. These measurements provide fundamental insight into carrier-phonon interactions in semiconductors. Unexpectedly large differences are found in the energy-loss rates for electrons and holes in GaAs/AlGaAs quantum wells. This large difference results from an anomalously low electron-energy-loss rate, which we attribute to the presence of nonequilibrium optical phonons rather than the effects of reduced dimensionality or dynamic screening.

  Title Energy distribution function of quasiparticles in mesoscopic wires Type Journal Article
  Year 1997 Publication Phys. Rev. Lett. Abbreviated Journal  
  Volume 79 Issue 18 Pages (up) 3490-3493  
  Keywords tunnel probe, metallic nanowire, diffusive wire, diffusive nanowire  
  Abstract We have measured with a tunnel probe the energy distribution function of Landau quasiparticles in metallic diffusive wires connected to two reservoir electrodes, with an applied bias voltage. The distribution function in the middle of a 1.5-μm-long wire resembles the half sum of the Fermi distributions of the reservoirs. The distribution functions in 5-μm-long wires are more rounded, due to interactions between quasiparticles during the longer diffusion time across the wire. From the scaling of the data with the bias voltage, we find that the scattering rate between two quasiparticles varies as <c9><203a>–2, where <c9><203a> is the energy transferred.

  Title Density of states in a superconductor carrying a supercurrent Type Journal Article
  Year 2003 Publication Phys. Rev. Lett. Abbreviated Journal Phys. Rev. Lett.  
  Volume 90 Issue 12 Pages (up) 127001 (1 to 4)  
  Keywords Usadel, superconducting nanowire  
  Abstract We have measured the tunneling density of states (DOS) in a superconductor carrying a supercurrent or exposed to an external magnetic field. The pair correlations are weakened by the supercurrent, leading to a modification of the DOS and to a reduction of the gap. As predicted by the theory of superconductivity in diffusive metals, we find that this effect is similar to that of an external magnetic field.
