If a dimensionless doping is sufficiently large, the superlattice behaves as a discrete system presenting front propagation failure and the wave fronts can be described near the threshold currents J(i) (i= 1,2) at which they depin and move. The wave front velocity scales with current as \J-J(i)\(1/2). If the dimensionless doping is low enough, the superlattice behaves as a continuum system and wave fronts are essentially shock waves whose velocity obeys an equal area rule.engjournal articlehttps//doi.org/10.1103/PhysRevE.64.036204http://arxiv.org/pdf/cond-mat/0201316.pdfopen access530.1Gaas-alas superlatticesElectrtic-field domainsCharge-density wavesBoundary-conditionsPropagationOscillationsDynamicsSystemsChaosFísica matemática
