FIG. 1.

Specular reflection of a phonon at the film-vacuum interface (z = d) and phonon refraction at the film-substrate interface (z = 0). The phonon incident at the interface z = 0 from the substrate is denoted with a dashed line. The angles of incidence θ1 and refraction θ2 are related by the equation . ρ (ρ′) and s (s′) denote the density and the speed of longitudinal sound for the film (substrate), respectively.

FIG. 2.

Schematic dependence of the oscillation amplitude of electron temperature |T 1| on the frequency of heat source ω. The solid and dashed lines correspond to effectively thick and thin films, respectively. It is assumed that the frequency of phonon-electron collisions ν(T 0) is small compared to the inverse time of electron-phonon energy relaxation .
