The manifestation of the self‐action potential in spatially heterogeneous structures is investigated theoretically. The expressions for the self‐action potential energy of a test charge placed in a central layer of the three‐layer structure or in either of the superlattice layers are obtained. The numerical results which correspond to the exact formulae are compared with the approximate ones which correspond to the analytical expressions, for which the criteria of validity are deduced from this comparison. The electron energy spectra are obtained from both, numerical and analytical calculations accounting for the self‐action potential energy. The applicability range of analytical results is established.
