Opis

This book is the latest to appear in a series documenting the progress of this exciting field in surface science. It presents recent results and reviews of the rapidly growing field of interaction of particles and lasers with solid surfaces leading to excitation, ionisation and desorption. The main emphasis is on the microscopic understanding of DIET, especially electron- and ion-induced desorption of adsorbed layers, emission from insulators, laser-induced desorption and ablation, photophysics and photochemistry. Applications ranging from laser ablation for medical purposes to DIET in high-temperature superconductors are also described.
