One of the most striking phemena in condensed matter physics is the occurrence of abrupt transitions in the structure of a substance at certain temperatures or pressures. These are first order phase transitions, and examples such as the freezing of water are familiar in everyday life. The conditions at which the transformation takes place can sometimes vary. For example, the freezing point of water is t always 0 C, but the liquid can be supercooled considerably if it is pure eugh and treated carefully. The reason for this phemen is nucleation. This mograph covers all major available routes of theoretical research of nucleation phemena (phemelogical models, semi-phemelogical theories, density functional theories, microscopic and semi-microscopic approaches), with emphasis on the formation of liquid droplets from a metastable vapor. Also, it illustrates the application of these various approaches to experimentally relevant problems. In spite of the familiarity of the involved phemena, it is still impossible to calculate nucleation accurately, as the properties and the kinetics of the daughter phase are insufficiently well kwn. Existing theories based upon classical nucleation theory have on the whole explained the trends in behavior correctly. However they often fail spectacularly to account for new data, in particular in the case of binary or, more generally, multi-component nucleation. The current challenge of this book is to go beyond such classical models and provide a more satisfactory theory by using density functional theory and microscopic computer simulations in order to describe the properties of small clusters. Also, semi-phemelogical models are proposed, which attempt to relate the properties of small clusters to kwn properties of the bulk phases. This mograph is an introduction as well as a compendium to researchers in soft condensed matter physics and chemical physics, graduate and post-graduate students in physics and chemistry starting on research in the area of nucleation, and to experimentalists wishing to gain a better understanding of the efforts being made to account for their data.
