A new breed of 'analyst' interested in characterizing surfaces, interfaces and thin films has emerged. His techniques include electron and ion spectroscopy/ microscopy (XPS, ESCA, UPS, AES, ELS, SIMS, ISS, SEM, SAM, ion probe etc.), Rutherford back scattering, reflec tion infrared spectroscopy, ellipsometry and electron microprobe analysis, EDXA, ion sputtering and methods of depth profiling. Development of these tech niques is rapid and often technology driven so that new knowledge is scattered. Surface and Interface Analysis is devoted to reporting developments and applica tions of techniques to meet the new needs of the materials scientist.
