Ultrafast optical response and inter-valley scattering in GaSb/AlSb quantum wells
We report femtosecond time-resolved differential transmission measurements of GaSb/AlSb quantum wells which reveal direct evidence of electron Gamma-L intervalley scattering. Raman measurements of non-equilibrium phonons generated by intra-Gamma electron relaxation yield a complementary picture of t...

| Özet: | We report femtosecond time-resolved differential transmission measurements of GaSb/AlSb quantum wells which reveal direct evidence of electron Gamma-L intervalley scattering. Raman measurements of non-equilibrium phonons generated by intra-Gamma electron relaxation yield a complementary picture of the carrier dynamics, confirming the measured intervalley scattering rate.
