Minimum thermal conductivity of superlattices
  • Simkin, Mahan
  • Materials Science, Physics
  • Physical review letters
  • 23 July 1999
The phonon thermal conductivity of a multilayer is calculated for transport perpendicular to the layers. There is a crossover between particle transport for thick layers to wave transport for thinExpand

Characterization of microvoids in device-quality hydrogenated amorphous silicon by small-angle x-ray scattering and infrared measurements.
The size, shape, and number density of microvoids in device-quality glow discharge deposited hydrogenated a-Si has been obtained by small-angle x-ray scattering (SAXS). By combining the SAXS resultsExpand

New Hydrogen Distribution in a-Si:H: An NMR Study.
Hot-filament-assisted CVD deposited {ital a}-Si:H with low H concentration and low defect density has been examined by {sup 1}H NMR. It is demonstrated for the first time that H microstructures canExpand

Electron-phonon contribution to the thermopower of metals.
  • Jonson, Mahan
  • Physics, Medicine
  • Physical review. B, Condensed matter
  • 15 November 1990
A theorem is proved for the thermopower when limited by the electron-phonon interaction. It is shown for simple metals that the thermopower is given by the Mott formula plus a correction term. TheExpand

Electron-electron interactions and the bandwidth of metals.
A calculation is presented of the self-energy of an electron from the screened exchange energy. Vertex corrections are included. They have a large effect upon the predictions of the width of theExpand

The Anharmonic Electron-Phonon Problem.
The anharmonic electron-phonon problem is solved in the infinite-dimensional limit using quantum Monte Carlo simulation. Charge-density-wave order is seen to remain at half filling even though theExpand
