SUBPICOSECOND REAL-SPACE CHARGE-TRANSFER IN GAAS/ALAS TYPE-II SUPERLATTICES
We report time-resolved anti-Stokes Raman scattering measurements of short-period GaAs/AlAs type II superlattices which reveal directly that q approximately 0 confined and interface optical phonons are emitted by electrons when they transfer from the Γ valley in the GaAs layers to the X, valley in t...
