Phonon-assisted tunneling and shot noise in double barrier structures in a longitudinal magnetic field

P. T. Anh, N. V. Hung and N. V. Lien

The phonon-assisted resonant tunneling is studied for the double barrier structures in a longitudinal magnetic field. Using the scattering matrix approach with an appropriate one-particle Green’s function we are able to calculate the current and the zero frequency shot noise power spectrum in a large range of the magnetic field and to any order of the electron–phonon interaction. Obtained results describe well the relevant experimental data and provide new suggestions for further examinations.
