Dispersion of electron-hole droplets in Ge
Astemirov T.A.. Bagaev V.S., Paduchikh L.l.D., Povarkov A.G.
The dispersion of electron-hole droplets in germanium is investigated under strong optical excitation at Τ = 2 °K. Some dynamic characteristics of the dispersion are reported and discussed. The experimental data agree with the theoretical model wherein the droplets drift in a stream of nonequilibrium phonons [L. V. Keldysh, Pis'ma Zh. Eksp. Teor. Fiz. 23, 100 (1976) [JETP Lett. 23, 86 (1976)] j. The constant that characterizes the strength of the "phonon wind" in Ge is determined.
