Surface analysis--the examination of the outer few nanometers of a material--is a routine undertaking in laboratories throughout the world, and is of great importance in such areas as corrosion, adhesion, polymer surface treatment, and microelectronics fabrication. This handbook provides an introduction to the two most popular surface analysis techniques: X-ray photoelectron spectroscopy and Auger electron spectroscopy. It explains the underlying physical principles, discusses instrumentation, and looks at the interpretation of resulting spectra. Applications of the two techniques are considered, and a critical comparison with other available methods is also included. This fully illustrated guide will be a valuable introduction for students and researchers in physics, engineering, and materials science.
