Zeeman perturbations on shallow acceptor states in germanium

Based on the effective mass theoretical approach, the magnetic field splittings of the shallow acceptor states in Ge have been studied. In this calculation, we have used the acceptor wave functions previously obtained by Mendelson and James. It is found that the g-factor for the ground state Î8 quartet, so obtained, is in close agreement with the one calculated by Suzuki, Okazaki and Hasegawa using full six component envelope functions. The Zeeman splitting for the excited Î6 doublet appears to be quite large. The g-factors for the Î7 doublet and other excited states have been calculated. The Zeeman splittings of Raman transitions involving the ground state multiplet and a low-lying excited state multiplet of even parity have also been determined.
