Surface Structure Study by High-Resolution Electron Microscopy and Diffraction
Abstract Structures of reconstructed surfaces and adsorbed layers are studied in-situ by UHV electron microscopy and diffraction. Transmission electron diffraction is useful for determining long range ordered structures such as Si(111)7×7 and also short range ordered structures using kinematical approximation. High-resolution electron microscopy at UHV can reveal local structures at atomic level resolution in transmission mode and at sub-nm resolution in reflection mode. Observations of the phase transition of Si(111) −7×7 to 1×1 and adsorption processes give finer information on structural details.
