Interface-phonon-mediated magnetopolaronic effect on impurity transition energies in quantum wells

Abstract

Electron interactions with interface phonon modes and strictly confined bulk phonon modes are considered to calculate the resonant magnetopolaronic 1s-2${\mathit{p}}_{+}$ transition energy of a hydrogenic impurity in the quantum well of a double heterostructure. An interaction gap is predicted between the bulk LO and TO frequencies, in constrast to the Fröhlich-type interaction. These results are in good agreement with recent experimental data.
