Reorganization energy associated with small polaron mobility in iron oxide

Effects of the spatial separation, leading to the noninteracting character of the donor and acceptor, on the reorganization energy associated with small polaron mobility in iron oxides were investigated. It was observed that reorganization energy plays an important role in controlling the electron transfer rates. It was also observed that a degree of interaction between the initial and final states was yielded by comparing the reorganization energies of 4-point method and direct method. The results show that the reorganization energy is expected to be constant 2.1 eV independent of ET distance by a 4-point method.
