In semiconductor alloys, fluctuations in composition broaden the exciton making the absorption features less distinct. However, the continuum absorption of the exciton still influences the absorption spectra, even when the excitonic features are no longer clearly visible. Therefore, a typical semiconductor's low-density absorption spectrum shows a series of exciton resonances and then a continuum-absorption tail.

Interestingly, the absorptance associated with each step is measured to be ∼1.6% OSTI.GOV Journal Article: Spatiotemporal dynamics of photon echoes from continuum states in semiconductors Title: Spatiotemporal dynamics of photon echoes from continuum states in semiconductors Full Record absorption with the Molecular Response Theory lineshape, based on physical principles and measurements, an accurate continuum absorption is obtained within four THz absorption windows, that agrees well with the empirical theory. The absorption is significantly smaller than that obtained using the van Vleck-Weisskopf lineshape with a 750 GHz cut responsible for the absorption, multiplied by the square of frequency [see, e.g., Clough et al., 1989; Ma a•rt Tipping, 1990]. Hence a reduced continuum absorption is defined here as c: - v-'o-3e, H20 (4) where ct is the total measured absorption in pure water vapor.
