摘要：

We have directly measured the carrier-density dependence and the temporal evolution of the band-gap renormalization in a suitably designed GaAs/AlxGa1-xAs quantum-well heterostructure. The transient behavior of the band-gap renormalization is governed by the carrier lifetime. Good quantitative agreement is found with the expected n1/3 carrier-density dependence. © 1990 The American Physical Society.
