Abstract
The dynamics of intervalley scattering of electrons is investigated in GaAs with 6 fs optical pulses at room temperature. We report the observation of a ‘‘resonant coupling’’ between the Γ and X conduction bands. This effect slows the apparent rate of scattering of carriers in the Γ valley at energies near the minimum of the X valley.Keywords
