H. Akbas et al., ACCEPTOR 1S-2P(+ -) TRANSITIONS IN GAAS/GA0.7AL0.3AS QUANTUM-WELLS - EFFECTS OF SPATIALLY DEPENDENT SCREENING UNDER ELECTRIC AND MAGNETIC-FIELDS/, Physica status solidi. b, Basic research, 205(2), 1998, pp. 537-542
The valence subband energies in the presence of an electric-field are
calculated using the fourth-order Runge-Kutta method. The 1s- and 2p(/-)-like acceptor states in the presence of a magnetic field are then
calculated variationally. The effects of the spatially dependent scree
ning function epsilon(r) on the calculation of the transition energies
are specifically investigated. The use of a constant epsilon(o) is sh
own to yield better agreement with experimental results.
