Direct observation of femtosecond intervalley scattering in GaSb: Electron-phonon scattering and continuum coherent transients
Femtosecond Γ-L intervalley electron scattering has been observed in bulk GaSb and GaSb/AlSb quantum wells using time-resolved differential transmission and Raman spectroscopy. The reverse process is found to occur on a significantly longer time scale due to long-lived Γ state occupancy. The results...
