Title Interpretation of a recent experiment on interference of photon beams Type Journal Article
Year 1968 Publication Phys. Rev. Abbreviated Journal
Volume 172 Issue 5 Pages (up) 1284-1285
Keywords
Abstract The interpretation of an important recent experiment by Pfleegor and Mandel according to the causal formulation of the wave-particle dualism is developed. This interpretation is simpler and seems more satisfactory than that provided by the current ideas on the nature of light.

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 Localization, superconducting fluctuations, and superconductivity in thin films and narrow wires of aluminum Type Journal Article
Year 1987 Publication Phys. Rev. B Abbreviated Journal Phys. Rev. B
Volume 35 Issue 7 Pages (up) 3188-3206
Keywords Al films; electron-phonon scattering; electron-electron scattering; Disordered structures; amorphous and glassy solids, Relaxation times and mean free paths, Galvanomagnetic and other magnetotransport effects
Abstract We report a comprehensive set of experiments on wide and narrow thin-film strips of aluminum which test the predictions of recent localization theory. The experiments on wide films in the two-dimensional regime confirm the theoretical predictions and also yield insight into inelastic mechanisms and spin-orbit scattering rates. Our extension of the existing theory for one-dimensional systems to include spin-orbit scattering and Maki-Thompson superconducting fluctuations is verified by the experiments. We find clear evidence for one-dimensional localization, with inferred inelastic rates identical to those in two-dimensional films. The prediction of the localization theory for a dimensional crossover from two-dimensional to one-dimensional behavior is also confirmed. We have reanalyzed the results of some previous experiments on thin films and narrow wires in light of these results.

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.
