摘要：
The quasi‐steady state hot LO‐phonon distribution function, as it is produced by hot electron cooling in laser excitation experiments, is calculated induding the effect of electron energy collision broadening (EECB) and screeing. Numerical computations performed in several compound polar semiconductors reveal a rather strong effect of EECB. Copyright © 1990 WILEY‐VCH Verlag GmbH & Co. KGaA
