Title: Mechanism For Lo-phonon Temperature Overshoot In Gaas
Author: Rego L.G.C.
Algarte A.C.S.
Abstract: Carrier relaxation and LO-phonon dynamics are investigated in GaAs crystals illuminated by picosecond laser pulses. It is evidenced that an overshoot of the LO-phonon quasitemperature above the electron quasitemperature can occur in the absence of intervalley scattering. This effect is ascribed to the screening of the polar optical interaction. © 1994 The American Physical Society.
