“…Note that distinctive features were observed in [15] in I-V characteristics of GaAs/AlGaAs SLs with thin barriers and wide enough QWs (at liquid He temperature), which were attributed to resonant (inter-miniband) tunnelling between the QWs located at several SL periods from each other. In contrast to that work, we have to admit for our SLs that, first, the possibility of electron tunnelling across 10-13 SL periods would be possible and, second, the maxima in I-V curves would not be equidistant.…”

The vertical transport in short-period InAs/AlSb and GaAs/AlAs superlattices was studied. The negative differential conductivity was observed in a miniband transport regime as a result of the overlapping of confined states in a periodic quantum well structure (Esaki-Tsu mechanism). Several maxima appeared on current-voltage characteristics of the superlattices found in the non-resonant tunnelling regime. They are shown to be due to the influence of the optical cavity on optical transitions within quantum wells (Purcell effect).

“…At same time, gain near the Bloch frequency still can exist without a population inversion between different minibands [lo]. Monte Carlo simulation with simplified scattering integral demonstrates that NDC exists for the frequencies greater than the Bloch frequency [9]. However, we should note that this result is based on representation of Zener tunneling as a scattering event.…”

“…The scheme of Bloch oscillator with an account of interminiband transitions has been suggested in [8,9].The main idea of this approach is that the Zener tunneling between two nearest minibands, separated by a small gap, changes a static VI characteristic of superlattice. [8,9].…”

The Bloch oscillator is a very promising suggestion for an inversionless Terahertz semiconductor laser, which was not still realized in an experiment. The principle of operation of this humble source of THz radiation is based on Bloch oscillations of miniband electrons in a biased semiconductor superlanice. The majority of researches attribute the difficulties in realization of the Bloch oscillator to a distmctive role of high-field domains inside a superlanice. In this report we present a minireview of different new approaches to the generalized Bloch oscillator, for which it is possible to reach gain due to the Bloch oscillations and simultaneously to avoid a formation of domains in a superlanice.
