Bulklike structures for medium-sized Aln (n=31–40) clusters

Abstract

Neutral aluminum clusters Al(n) (n=31-40) were studied using a genetic algorithm (GA)/tight-binding (TB) search combined with DFT-PBE calculations. It is found that the medium-sized aluminum clusters Al(31) to Al(40) exhibit a bulklike stacking pattern. Anion clusters were also studied.
