• The Hall effect of the acoustic polaron is theoretically classified into four types according to the strength of electron-phonon coupling. The first type for the weak coupling corresponds to the band conduction of large polarons. In the second type, although the small polaron is energetically stable, thermally populated large polarons play dominant role in the drift and Hall conductions. In the third type, the drift conduction is determined by the thermally activated hopping of small polarons while the Hall conduction is still due to thermally populated large polarons. In the last type for the strong coupling, the Hall conduction is also determined by the small polaron hopping. Except in the first type where the Hall to drift mobility ratio is a constant of order unity, the ratio is large compared with unity, with significant temperature dependence. The type change with increasing coupling is described in a unified treatment for polarons.
