Peculiarities of electron spectrum renormalized by optical phonons in the cascade of quantum cascade detector

Abstract

In the model of position-dependent e(cid:27)ective mass of an electron and isotropic dielectric continuum for con(cid:28)ned and interface phonons, the Hamiltonian of the electron-phonon system is obtained in the representation of the second quantization energy di(cid:27)erences are close to the energies of longitudinal phonons, and the state of the (cid:16)phonon ladder(cid:17) of extractors.
