The electronic energy band structures for beta-ZrNCl and beta-HfNCl. which can be superconducting by intercalation, have been calculated by using the scalar-relativistic full-potential linearized augmented-plane-wave method within the local-density approximation. Intercalation derives the change of crystal structure and thus the change of electronic structure. Both these two compounds show two-dimensional electronic structure. The doping dependence of T-c can be explained by the rigid-band model. (C) 2000 Published by Elsevier Science B.V. All rights reserved.
