The effect of the Coulomb interaction on the dielectric function, the mobility, and the energy spectrum of gapless semiconductors is analyzed. It is shown that the hole energy is strongly renormalized due to the nonlocality of the potential. The resulting shape of the valence band and its dependence on the electron concentration is considered. The nonlocality of the lattice potential diminishes the ground state energy of the acceptor.
