Reentrant morphology transition in the growth of free silver nanoclusters
The growth of free silver nanoclusters is studied by molecular dynamics simulations, from a small seed up to sizes N approximately 150. It is shown that the final outcome of the growth process depends crucially on the growth conditions (deposition flux straight phi and temperature T). A reentrant morphology transition is obtained: at intermediate values of T and straight phi a "decahedral window" is found; the window is surrounded by regimes where icosahedra are preferentially grown.
