A generalization of the energy‐loss transport concept, which includes carrier–carrier‐scattering, is applied to a thin (two‐dimensional) Bi‐film deposited on an e.g. CaF 2 ‐substrate. In particular, scattering by ions is considered and by charge density fluctuations. An additional scattering channel is taken into account by a scattering frequency ω τ . If the concentrations of electrons and holes are about equal, the resulting resistance of the Bi‐film at not too low temperatures is governed by scattering by fluctuations.
