Abstract

Using transient differential transmission measurements we probe directly the temporal evolution of band-gap renormalization of a photoexcited modulation-doped quantum-well system. The band-gap renormalization is shown to increase while the carriers cool down towards the lattice temperature. The experimental results for the band-gap renormalization are in qualitative agreement with calculations made using the random-phase approximation.
