Luminescence studies of photoexcited electron-hole plasmas in silicon and germanium
… shell of plasma. Both of these facts point to a phonon-wind driven transport; phonons created in the hot-carrier thermalization process near the excitation region move ballistically into the crystal at low temperatures and drag the carriers with them i.e., the carriers are driven into the crystal …

Interaction of non-equilibrium phonons with electron-hole plasmas in germanium
… results of experiments on the interaction of phonons and photo-excited electron-hole plasmas in Ge at low temperature. The first two studies involve the low temperature fluid phase known as the electron-hole liquid (EHL). The third study involves a wider range of temperatures and includes the …

I. Excitonic phase diagram in Si: evidence for two condensed phases ; II. Motion of photoexcited carriers in GaAs/Alx̳Ga1̳-̳x̳As multiple quantum wells : anomalous confinement at high densities
… possibly indicating defect-limited diffusion or phonon-wind effects. Above this density the spatial profiles exhibit two distinct components with widely differing diffusivities. This remarkable behavior may be understood with consideration of the interactions of non-equilibrium phonons with the …
