Abstract : The program of research was concerned with the study of the structure of perfect surfaces and defect distribution near surfaces. The study of perfect surfaces is a necessary preliminary to the investigation of more complicated systems involving for example adsorption from the gas phase. For this part of the work, the method of low energy electron diffraction was used as the principal experimental technique. Defects near ionic crystal surfaces have been studied by measurements of surface potential on single crystals of various orientations. The process of surface diffusion which involves mobile defects has been studied by a mass transport method developed during the course of this investigation. (Author)
