Abstract
The vibrations of small clusters of atoms are studied using self-consistent boundary conditions which simulate the infinite medium. The Born model for Si and Ge is used with nearest neighbour central and non-central forces. An external potential is imposed upon the surface atoms and the coefficients appearing in this potential are determined by demanding that the mean square amplitude of vibration of the surface atoms is the same as that of the interior atoms. As an example, the procedure is applied to five atoms in a tetrahedral arrangement, i. e. one interior and four surface atoms.
