Earlier books on this subject, i.e. "Sputtering by Particle Bombardment I - III" are nearly 20 years old, but since then a lot of new and important work has been performed and published in international journals. The planned book brings an overview about all the new results to provide a state-of-the-art report covering theoretical as well as experimental aspects of sputtering. This concerns especially a new summary of the measured and calculated sputtering yields with an algebraic approximation formula for the energy and angular dependence of the yields. This is especially useful for all colleagues, who need sputtering yields for physics and/or applied problems.
