Abstract
Some factors influencing phase transitions in thin films deposited by vacuum evaporation are discussed, particularly the role of size-effect in phase transitions. The existence of a minimum total surface energy requirement is shown to lead to the formation of phases in thin films which are unstable in bulk samples; subsequent transitions to phases of higher symmetry being observed with decreasing thickness together with aggregated films consisting of discrete particles. In the limiting case of small dimensions the condition for the minimum total surface energy requires f.c.c. lattice phases and at high and low temperatures, liquid and amorphous phases, respectively, are formed.
