Abstract
It is shown that, in alternant lattices with a half-filled nondegenerate tight-binding band, the static zero temperature dielectric function diverges logarithmically for a wavevector Q=( pi , pi , pi ) in the reciprocal lattice. This implies that such three-dimensional systems may distort in a way which results in a non-conducting ground state.
