Annotation
The course of Surface Physics comprises physical properties of solid surfaces, their geometrical and electron structure. Work function of solid surfaces, the phenomena occurring under irradia-tion of surfaces, electron and ion impact and the influence of electric field and high temperature on surfaces are thoroughly treated and explained.
A brief survey of secondary emission mecha-nisms as well as analytical methods based on these phenomena is also given.
