Interaction of Electrons with Confined Phonons in Multilayer Resonant Tunneling Structure
Journal Title: Фізика і хімія твердого тіла - Year 2014, Vol 15, Issue 1
Abstract
The theory of electron stationary spectrum and wave functions in plane multilayer resonant tunneling structure placed into the electric field is developed using the model of the active band of the quantum cascade laser. For the same nanostructure the theory of confined optical phonons spectra is established within the dielectric continuum model. Using the obtained electron wave functions and phonon polarizational potentials the theory of electron – confined phonons interaction in multilayer nanostructure is developed. The Hamiltonian of this interaction is obtained in the representation of second quantization. The calculations of the electron and the phonon spectra and potential of polarization of confined phonons are performed for the experimental resonant tunneling structure. The partial shifts are calculated for the electron spectrum renormalized by the interaction with confined phonons. The obtained results are in good correlation with the experimental data.
