“…been studied [2][3][4][5][6], and the anisotropy of the Fermi surface (and hence of the cyclotron mass) in these systems is well known. Investigations of superlattices with a single, only partially populated miniband showed that the effective mass for the movement along the axis of the superlattice is enhanced relative to the bulk value [2].…”

The cyclotron mass in periodically delta-doped InP was studied, using the temperature dependence of the Shubnikov-de Haas (SdH) effect in tilted magnetic fields. The samples had two populated minibands, E 1 and E 2 , both of which contributed with oscillatory components to the SdH spectrum. When the magnetic field is tilted from the direction parallel to the axis of the superlattice, the cyclotron mass associated with E 1 electrons increases, as expected for a quasi-two-dimensional system. In contrast, the cyclotron mass of E 2 electrons decreases. This decrease is due to Bragg reflections of electrons by the superlattice, which lead to shorter orbits when the magnetic field is tilted. It is estimated that in periodically delta-doped semiconductors the cyclotron mass can decrease at most by a factor of three when the magnetic field is rotated by π/2.

The oscillatory part of the conductivity along the con6ning planes of a superlattice miniband under a perpendicular quantizing magnetic 6eld was calculated, assuming a tight-binding approximation for the miniband dispersion. The manifestation of the belly and neck cross sections of the Fermi surface is studied as a function of the broadening of the electronic energy levels, miniband widths, and energy minigaps. The efFects of the deviation from the nearest-neighbor tight-binding approximation upon the line shape of the magnetoresistance are studied. The model presented allows for a quantitative description of the magnetoresistance spectra and is in good agreement with recent experimental observations on InAsi, Sb /InSb doped superlattices and GaAs with a periodical planar doping of silicon.
