Öğe Acceptor 1s-2p± transitions in GaAs/Ga0.7Al0.3As quantum wells: Effects of spatially dependent screening under electric and magnetic fields(Wiley-VCH Verlag, 1998) Akbaş H.; Aktaş S.; Okan S.E.; Ulaş M.; Tomak M.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 screening function ?(r) on the calculation of the transition energies are specifically investigated. The use of a constant ?0 is shown to yield better agreement with experimental results.
