Abstract
Using the model of an elastic continuum, precise analytical solutions of the equations of motion are established and a theory of the spectrum and components of the displacement field of acoustic phonons is developed for a two-well resonant-tunneling nanostructure with AlN – quantum barriers and GaN∕AlxGa1−xN – quantum wells. For the experimentally realised nanostructure – the active zone of a quantum cascade detector – depending on its geometric parameters, the spectrum of acoustic phonons and normalized components of the displacement fields were calculated.
