Surface Vibration Spectroscopy
Surface science is an interdisciplinary field which encompasses the physics of solids, molecules, and atoms, their chemistry, as well as the material sciences. Applications of surface science branch into design and engineering of devices, micromechanics, sensorics, tribology, catalysis, and electrochemistry. Traditionally, surface physics has dealt with the solid vacuum interface, however, more recently we find increasing activity in solid-solid interfaces, solid-liquid interfaces, multilayered material, and also a revitalization of traditional fields like the physics of thin films, crystal growth, and epitaxy. The development of surface science has brought about an impressive number of ingenious methods for probing surfaces and interfaces. A common aspect of all these methods is that the tools need to be specific to surface properties, that is, they need to discriminate between surface and bulk properties and be less sensitive to the latter by a large margin. The use of nonpenetrating, strongly interacting particles with matter is therefore widespread. Traditionally, electrons have played a major role in the methodology of various tools. More recently, the use of atoms and ions have added to the arsenal of techniques.
