In this paper, we examine two features of acceptor states in GaAs doping superlattices. First, we consider how the finite size of acceptor state wavefunctions affects optical matrix elements and below-gap luminescence spectra. Next, we examine the finite width of the acceptor band caused by potential fluctuations associated with the random configuration of charged impurities in the system and discuss the impact of this width on luminescence.
