Abstract

The time evolution of the electron population in the bottom of the X ₆ valley in Al_0.6Ga_0.4As was obtained by a femtosecond visible-pump and infrared (IR)-probe absorption spectroscopy. The L₆ to X₆ intervalley scattering time of approximately 200 fs was determined from the measured kinetic data. The role of the L₆ to X₆ intervalley scattering for the relaxation process of hot carriers was revealed.
