Beats of the Magnetocapacitance Oscillations in Lateral Semiconductor Superlattices

We present calculations on the magnetocapacitance of the twodimensional electron gas in a lateral semiconductor superlattice under two-dimensional weak periodic potential modulation in the presence of a perpendicular magnetic field. Adopting a Gaussian broadening of magnetic-field-dependent width in the density of states, we present explicit and simple expressions for the magnetocapacitance, va...

Impurity binding energies in semiconductor Fibonacci superlattices

We have calculated the density of states (DOS) of a GaAs–GaAl superlattice whose ratio between the potential energy of the impurities and the potential energy of the atoms at the lattice is a nth power of the golden mean t 1⁄4 ð1 þ ffiffi 5 p Þ=2; ðn 1⁄4 1; 2; 3;...Þ: Our theory uses Dyson’s equation together with a transfer-matrix treatment, within the tight-binding Hamiltonian model. The elec...

Miniband transport and oscillations in semiconductor superlattices

We present and analyse solutions of a recent derivation of a drift-diffusion model of miniband transport in strongly coupled superlattices. The model is obtained from a single-miniband Boltzmann–Poisson transport equation with a BGK (Bhatnagar–Gross–Krook) collision term by means of a consistent Chapman–Enskog expansion. The reduced drift-diffusion equation is solved numerically and travelling ...

Electroabsorption spectroscopy of effective-mass AlxGa12xAs/GaAs Fibonacci superlattices

Effective-mass Fibonacci superlattices are composed of quasiperiodic sequences of weakly coupled quantum wells in which the transfer-matrix element is significantly smaller than the confinement energy, which is significantly smaller than the confining potential. We identify several distinct classes of quasiperiodic superlattices that are distinguished by diagonal vs off-diagonal quasiperiodicit...
