Abstract
The acceptor-related photoluminescence spectrum of a GaAs quantum-wire microcrystal is investigated theoretically using a model calculation within the effective-mass approximation, with the acceptor envelope wave functions and binding energies calculated by a variational procedure. Typical theoretical photoluminescence spectra show two peaks associated with transitions from the n=1 conduction-subband electron gas to acceptors at the on-center and on-edge positions in the wire, in good agreement with the recent experimental results by Hiruma et al. [Appl. Phys. Lett. 59, 431 (1991)].
