Abstract

The X valley plays an important role in hot carrier transport in GaAs [1, 2]. In this paper, we present pump—probe IR absorption measurements to determine the time evolution of electrons in the X 6 valley, the upper limit of the X 6 → Γ 6 scattering time t xΓ the energy separation of the X 6 and X 7 bands at their minima Δ 7–6, and the density of states effective mass of the Xz valley.
