Unter Epitaxie versteht man das orientierte Aufwachsen dunner Schichten auf einer kristallinen Unterlage. Im Idealfall erreicht man einkristalline Schichten, welche die Kristallorientierung der Unterlage fortsetzen. Bei der Aufdampf- methode mu man in der Regel erhohte Temperaturen der Unterlage wahrend des Aufdampfprozesses anwenden, um Epitaxie zu erreichen. In vielen Fallen spielen auch Adsorptionsschichten auf den kristallinen Unterlagen eine Rolle. Zum Bei- spiel wurde in der vorliegenden Arbeit die Epitaxie von Eisenschichten auf Stein- salz-Spaltflachen durch den H 0-Partialdruck...

The aim of this monograph is to outline the physics of image formation, electron-specimen interactions, and image interpretation in transmission el- tron microscopy. Since the last edition, transmission electron microscopy has undergone a rapid evolution. The introduction of monochromators and - proved energy ?lters has allowed electron energy-loss spectra with an energy resolution down to about 0.1 eV to be obtained, and aberration correctors are now available that push the point-to-point resolution limit down below 0.1 nm. After the untimely death of Ludwig Reimer, Dr. Koelsch from...

Energy-Filtering Transmission Electron Microscopy (EFTEM) presents a summary of the electron optics, the electron-specimen interactions, and the operation and contrast modes of this new field of analytical electron microscopy. The electron optics of filter lenses and the progress in the correction of aberrations are discussed in detail. An evaluation of our present knowledge of plasmon losses and inner-shell ionisations is of increasing interest for a quantitative application of EFTEM in materials and life sciences. This can be realized not only by filtering the elastically scattered...
