Reorganization energy in electron transport through semiconductor quantum dots

The concept of reorganization energy is well established for molecular systems where the electron transfer from a donor to an acceptor is accompanied by the reorganization of environment. It is not the case for bulk semiconductors with translational symmetry. However, in the presence of additional confinement, like in the quantum dots, the electron-phonon interaction is modified. We show that when the dots are not identical, the phonon reorganization energy can be determined. We calculate it for a realistic case of GaAs quantum dots.
