Abstract

The electronic structures of Sr_14-xCa_xCu24O41 are calculated within the local density approximation. Around the Fermi energy there exist quasi-one-dimensional bands originated from the ladder and chain layers. The nearest-neighbor inter-ladder hoppings are estimated to be 5--20% of the intra-ladder ones. Possible effects of Ca substitution on electronic structures and charge distribution are also discussed.
