摘要：

Subpicosecond laser pulses have been used to excite and probe photoexcited hot-electron plasma in In0.53 Ga0.47 As by Raman scattering. Hot-electron temperatures have been measured as a function of the length of subpicosecond pulses. Cooling of the hot electrons is compared with a model calculation in which the cooling mechanism is dominated by intervalley scattering. The Γ to L intervalley deformation potential in In 0.53 Ga0.47 As was determined to be around 3.5×108 eV/cm.
