Popyk T. Low-Energy Electron Scattering by Solid Surface

Object of investigation: metals, semiconductors, evaporated films, adsorbed molecules. The aim of investigation: elaborating physical fundamentals of low-energy electron backscattering (LEEBS) technique, construction of equipment for its practical realization, testing the technique for obtaining fundamental characteristics of solids. Methods and facilities for investigation: low-energy electron backscattering; trochoidal and hypocycloidal electron spectrometers. Theoretical and practical results, new features: trochoidal and hypocycloidal electron spectrometers are worked out, fine structure in the LEEBS spectra of solid surface is revealed, the correlations with the specific features of the band structure being found. The degree of implementation: planned. The field of application: semiconductor electronics, material science.
