AbstractThe standard relationship between band-edge position and flat-band potential for a non-degenerate semiconductor is based on rigid-band model. We theoretically show that this standard relationship gives invalid band-edge positions for small-polaron semiconductors, and propose a new one based on small-polaron model. The reassigned band-edge positions and the small-polaron band are crucial to properly understand pure and/or lattice-coupled electronic processes of photo-induced interfacial charge transfer for small-polaron semiconductors. Applications are demonstrated in small-polaron-like rutile and rigid-band-like anatase TiO2, in which we rationalize the dilemma of charge transfer at rutile/anatase interface in mixed-phase TiO2 for photocatalysis, and revisit the electron-injection process in dye-sensitized TiO2 solar cells.
