摘要：

The electrides are a peculiar class of ionic solids where the anions are replaced by electrons. The physical reasons for the stability of such an unconventional situation are explored on the basis of a self-consistent tight-binding Hartree-Fock calculation. The theoretical results are shown to provide a natural explanation for the formation of a lattice of trapped electrons. They also lead to correct predictions for the optical absorption spectrum and the Knight shift. © 1990 The Japan Society of Applied Physics.
