摘要：
The theory of the intrinsic Urbach tail absorption in semiconductors is discussed. Some recent results of a cumulant expansion up to second order are presented which fit experimental observations excellently. The results can be simulated with a frequency‐dependent broadening which gives rise to memory effects for the optically induced polarization. The importance of these effects for the understanding of the pulsed nonresonant optical Stark effect is discussed. Copyright © 1990 WILEY‐VCH Verlag GmbH & Co. KGaA
