Photoacoustic, Photothermal and Photochemical Processes at Surfaces and in Thin Films

Photoacoustic, Photothermal and Photochemical Processes at Surfaces and in Thin Films provides a comprehensive treatment of the latest developments in this field. Topics covered include laser-induced desorption, ablation and surface damage; surface acoustic waves; photothermal and photoacoustic characterization of thin films and interfaces; depth profiling in the frequency and time domains; remote testing and nondestructive evaluation; materials characterization, for example of ferromagnetic films; and new theoretical approaches applying the concept of fractals.
