THE DIRECT ABSORPTION EDGE IN COVALENT SOLIDS
Comparative measurements of the absorption edge of p-type GaAs and compensated GaAs over a wide temperature range demonstrate that the shape of the edge in such materials is not dependent on phonon interactions, and is attributable to the state of charge of impurities in the material.
