Kapitza resistance at the liquid—solid interface

Kapitza resistance at the H↓/liquid He interface

2014 In spin-polarized atomic hydrogen, the way to low T and high density is restricted by the Kapitza resistance. This is calculated, together with the corresponding characteristic time, for one channel : from H gas to liquid helium ripplons. J.

Appraisal of the Cmn/helium Kapitza Resistance

It is argued that the thermal resistance between cerium magnesium nitrate (CMN) and pure He,He containing He* impurity or dilute He in He"* can be understood in terms of the phonon bottlenecked spin-lattice resistance within the CMN and a size dependent thermal boundary resistivity. The fact that emerges is that the phonon bottleneck within the CMN is strongly dependent upon whether the CMN is ...

Diffuse reflection of phonons and the anomalous Kapitza resistance

High-resolution time-of-flight phonon-reflection spectra in sapphire crystals are analyzed with the aid of detailed numerical calculations. It is argued that spectra from vacuum interfaces may be understood if about half the incident phonons are assumed to be reflected specularly, the remainder diffusely. A simple model of the effect on spectra of diffuse scattering is presented and compared to...

Kapitza resistance and the thermal conductivity of amorphous superlattices

Temperature relaxation and the Kapitza-boundary-resistance paradox.

The calculation of the Kapitza boundary resistance between dissimilar harmonic solids has since long (Little [Can. J. Phys. 37, 334 (1959)]) suffered from a paradox: this resistance erroneously tends to a finite value in the limit of identical solids. We resolve this paradox by calculating temperature differences in the final heat-transporting state, rather than with respect to the initial stat...
