The Nature of Defects on Solid Surfaces as Studied by Electron Spectroscopy

  • Victor E. Henrich
Part of the NATO ASI Series book series (NSSB)

Abstract

The study of bulk defects in solids has been an active area of both experimental and theoretical research for many years, and as the other articles in this volume attest, a great deal is known about them and their properties. Our understanding of surface defects on solids is, on the contrary, in its infancy. The whole field of surface science has only blossomed during the last 15–20 years, largely because the experimental techniques necessary for the controlled study of surfaces, including ultrahigh vacuum (UHV), were not previously widely available. With the advent of commercial UHV systems and surface-sensitive electron spectrometers of various types ,a growing segment of the scientific community began trying to unravel the mysteries of the physics and chemistry of surfaces. As with any new field, the logical starting point was the study of simple systems,i.e., nearly perfect single-crystal surfaces. Work on perfect surfaces served as a proving ground for both the new experimental techniques and theoretical approaches. An extremely important aspect of surface science is the interaction of surfaces with adsorbed molecules, and studies in that area also began by using perfect surfaces as substrates.
