Effect of interfacial roughness on phonon radiative heat conduction.

Type of article: Article

Summary

The interface between a solid and a liquid or two dissimilar solids poses a resistance to heat transport by phonons. The classical theory explains that the resistance arises due to a mismatch in acoustic impedances of the two media. This study explains these observations in the temperature range of 0.06-1 K and helium 3 pressure range from zero atmosphere in liquid state to solid state, by including the effects of surface roughness and phonon attenuation in solids by electrons or dislocations.
