Abstract
We examine the electronic states of A 14− x Ca x Cu 24O 41(A Sr,La) by the ionic and cluster model approach. Through the analysis of Madelung energy calculation, it is found that self-doped holes for A Sr are likely to stay on the chain at x = 0 and the Ca substitution drives the holes to move to the ladder. The optical conductivity is calculated applying the exact diagonalization method to small cluster. The calculated results provide consistent explanation to recent experiment.
