Abstract
We have modelled the scattering of heat pulses from rough surfaces, as observed in reflection experiments. The effect of long-range irregularities was calculated in the eikonal approximation. For diffusive scattering from short-range irregularity, an analytic expression was obtained which is valid in the most common experimental arrangements. The model was used to interpret data obtained in heat pulse experiments on buried interfaces in silicon.Keywords
