Abstract :
There are only a few experimental reports on measurements of the Stark effect on shallow acceptors. We show that measurements of the degree of circular polarization of the luminescence originating from a free-to-bound Γ 6 → Γ 8 transition allows us to determine the dipole moment of a substitutional acceptor in a crystal of T d symmetry. We suggest the performance of such experiments in a single GaAs/GaAlAs heterostructure δ -doped with acceptors. Thus we propose an experimental method for investigation of the Stark effect in solids.
