Kapitza conductance and heat flow between solids at temperatures from 50 to 300 K

Stoner, R. J., Maris, H. J.·1993·Physical Review B

Abstract

Measurements of the Kapitza conductance ${\mathrm{\ensuremath{\sigma}}}_{\mathit{K}}$ made using a picosecond optical technique at temperatures between 50 and 300 K are presented for interfaces between metals and dielectrics. The Debye temperatures ${\mathit{FTHETA}}_{\mathit{D}}$ of the metals (Pb, Au, Al, and Ti) were in the range from 102 to 426 K, while those of the dielectrics (${\mathrm{BaF}}_{2}$, sapphire, and diamond) varied from 287 to 2200 K. Conductances measured between materials with ${\mathit{FTHETA}}_{\mathit{D}}$ differing by less than about a factor of 5 were found to be in reasonable agreement with calculations based on a lattice dynamical theory. However, for more widely mismatched solids the measured conductances were found to be greatly in excess of the lattice dynamical calculations. In some of these cases the conductances exceeded even the phonon radiation limit, indicating that much of the heat flow between the solids was via an inelastic channel. It was demonstrated experimentally that the inelastic channel does not involve an interaction between the phonons in the dielectric and electrons in the metal. We show that the anomalously large conductance can be understood in terms of a model in which the anharmonicity of the metal plays an important role.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
