Statistical Physics of Nanoparticles in the Gas Phase

This book examines the fundamental properties of nanosystems in the gas phase. Detailed derivations of results illustrate the applicability and limitations of approximations and demonstrate the power of the methods.

Thermal processes are ubiquitous and an understanding of thermal phenomena is essential for a complete description of the physics of nanoparticles, both for the purpose of modeling the dynamics of the particles and for the correct interpretation of experimental data.

The second edition of this book follows the logic of first edition, with an emphasis on presentation of literature results and to guide the reader through derivations. Several topics have been added to the repertoire, notably magnetism, a fuller exposition of aggregation and the related area of nucleation theory. Also a new chapter has been added on the transient hot electron phenomenon.

The book remains focused on the fundamental properties of nanosystems in the gas phase. Each chapter is enriched with additional new exercises and three Appendices provide additional useful material.

Provides a didactical guided tour of many interesting phenomena and properties of free clusters and nanoparticles Explores the limits of the mathematical approximations and demonstrates the power of the statistical physics method Enriched with 125 exercises and over one hundred figures Includes fundamental results, applications, illustrative examples and three useful appendeces
