Abstract

Formulae are derived for the excess free energy of cylindrical and pill-box nuclei under homogeneous and heterogeneous conditions. The surface free energy is taken to be different for lateral and end surfaces of the nucleus in deriving the critical dimensions. The effect of pressure on the formation of a nucleus is studied theoretically first for the appearance of a new phase from a gas and then for a condensed phase.
