In this paper, we compare transmission spectra of electrons propagated in ballistic transport regime in finite conventional and finite effective-mass superlattices. Taking into account the off-center-zone transport as well as center-zone one, we show theoretically that the Bragg transmission of carriers and the kinetic confinement effect are presented not only in the effective-mass superlattice but...
To predict output optical characteristics of quantum-cascade lasers, it is necessary to model dynamics of electrons, holes and photons including into consideration non-equilibrium regime. There are several approaches to modeling of the dynamics of the carrierspsila distribution: one method is based on non-equilibrium Greenpsilas functions [C.S. Lee and A. Wacker, Phys. Rev. B, 66, 245314 (2002)],...
The new structure for management of carriers' ballistic transport have been proposed. This structure is based on effective-mass superlattice. The paper contains results which represent transmission coefficient spectra corresponding to center and non-center ballistic transport in considered structure.
