| Abstract: | A quasirelativistic model of the narrow-gap semiconductor is considered. The interaction of the Dirac electron field with the non-dispersive phonon field in the short-range external potential (impurity) is taken into account. The classical solutions corresponding to the discrete spectrum are found. The fermion vacuum polarization effect is studied within the one-loop approximation. |
