A microscopic theory is presented for high-field miniband transport in a two-dimensional superlattice. The energy transfer to the lateral electron motion is taken into account as well as scattering on polar optical phonons. Oscillatory current anomalies appear when the optical phonon frequency is a
The minibands of p-type Ξ΄-doping superlattices (SLs) in GaAs are studied in dependence on acceptor sheet doping concentrations N A and SL periods d. The calculations rely on effective mass theory, applied to the 8 valence band hole gas. Hole-hole interaction is selfconsistently taken into account, i
