“…Actually, the study of electron tunneling processes in planar semiconductor multilayer resonant tunneling structures (RTS) occupies an important place for an effective work of modern quantum cascade lasers (QCL) [1][2][3] and detectors (QCD). Much attention is paid to the theoretical study of interaction of electrons with optical phonons [4], constant electric [5,6] and magnetic field [7] with the electron beam and its static and dynamic spatial charge [8,9], but the acoustic phonons influence on the resonant tunneling is still practically unexplored. Also the value of contribution of electrons interaction with acoustic phonons in multilayer RTS is not been studied yet.…”

Based on the elastic continuum model, the theory of displacement of acoustic phonons spectra, arising in flat semiconductor nanostructures, was developed. For the studied resonant tunneling structure, which can be an active element of a quantum cascade laser or detector, the spectrum of acoustic phonons modes has been calculated. The dependences of the acoustic phonon spectrum from geometric parameters of studied nanostructure were set. The results obtained in the paper can be used to further theoretical studies of the electrons interaction with the transverse acoustic phonons in multilayer semiconductor nanosystems.
