Atomic Clusters: From Gas Phase to Deposited brings together a series of chapters, prepared by acknowledged experts in their fields. Both fundamental and practical aspects are addressed of the physics and chemistry of a novel state of matter, namely clusters of small numbers of atoms of nanometre dimensions. This is a field of nanoscience that existed before the word was invented, but has particularly achieved major advances in the recent years.
* Contributions from leading experts in solid surfaces research * Cluster science is concerned with the properties of materials on the nano-metre scale * Brings together work on both free (gas-phase) clusters and those deposited on surfaces
This is a research-led volume directed to the research community in academic science but also highly relevant to areas of applied physics and chemistry.
