Effects of electron-interface-phonon interaction on resonant tunnelling in double-barrier heterostructures

Abstract
The tunnelling current through a resonant tunnelling structure is calculated including electron-interface-phonon coupling in the quantum well. The Hamiltonian describing electron-phonon interaction in a double-barrier structure is derived using the dielectric continuum model. The result shows that interface phonons of the barrier play a significant role in the double-barrier structure whose barrier width is greater than the well width.
