The Investigation of the Properties of Thin Films by Means of X-rays


THERE are a number of problems of the highest -L importance which are, or can be, contained in the study of what we often call the “thin film.” They are linked together by the fact that most reactions between bodies are largely determined by what takes place at their points of contact, and therefore by the nature of their surfaces. What is to be found in the interior of the body is often of much less importance than the composition and state of its surface film. The immensely varied problems of surface tension are examples of one kind: the phenomena of catalysis, of friction and lubrication are examples of other kinds.
