Abstract
The effect of the cluster surface on the ground state electronic properties of CdSe nanoclusters is calculated using a tight‐binding method. The calculation of optical matrix elements between selected surface and interior states is described. We find that the density of states is strongly dependent on the nature of the cluster surface and that there is a significant probability of an optical transition into unoccupied surface states.
