✦ Synopsis

We have investigated the atomic and electronic properties of spherical ideal SiN clusters (N = 5-417) using the empirical many-body potential energy function consisting of two-and three-body interactions, and by empirical tight-binding calculations, respectively. It has been found that the average interaction energy per atom decreases as the cluster size increases, and it becomes almost constant after the size N ¿275. On the other hand, the band gap shows cluster size dependent characteristics; the band gap decreases as the cluster size increases.

The resonant charge transfer (RCT) between a hydrogen anion and a cluster of aluminum atoms is investigated by means of the wave-packet propagation method that does not exploit the perturbation theory. The RCT on a spherical cluster is found to exhibit quantum size effects due to the finite size of
