Scanning Electron Microscopy provides a description of the physics
of electron-probe formation and of electron-specimen interactions.
The different imaging and analytical modes using secondary and
backscattered electrons, electron-beam-induced currents, X-ray and
Auger electrons, electron channelling effects, and
cathodoluminescence are discussed to evaluate specific contrasts
and to obtain quantitative information.
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
Springer- Verlag asked me if I would be willing to prepare a new
edition of the book. As it had served me as a reference for more
than 20 years, I agreed without hesitation. Distinct from more
specialized books on speci?c topics and from books intended for
classroom teaching, the Reimer book starts with the basic
principles and gives a broad survey of the state-of-the-art
methods, comp- mented by a list of references to allow the reader
to ?nd further details in the literature. The main objective of
this revised edition was therefore to include the new developments
but leave the character of the book intact. The presentation of the
material follows the format of the previous e- tion as outlined in
the preface to that volume, which immediately follows. A few
derivations have been modi?ed to correspond more closely to modern
textbooks on quantum mechanics, scattering theory, or solid state
physics.
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 electrons but mainly by imgaging and
analyzing with inelastically scattered electrons at different
energy losses up to 2000 eV. The strength of EFTEM is the
combination of the modes EELS, ESI, ESD and REM.

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 muss 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 begunstigt. 2 Das praktische Interesse
an einkristallinen Schichten beruht darauf, dass deren
physikalische Eigenschaften besser mit denen des kompakten
Materials zu ver gleichen sind als polykristalline Schichten mit
regelloser Kristallorientierung, die man beim Aufdampfen auf
amorpher Unterlage (Glas oder Kunststoff-Folien) er halt. In der
vorliegenden Arbeit sind die Bedingungen untersucht, unter denen
ein kristalline Wismut- und Eisen-Aufdampfschichten zu erhalten
sind. Wismut zeigt wegen seiner Grenzstellung zwischen Metallen und
Halbleitern einen relativ grossen Hall-Effekt, der ausserdem sehr
anisotrop ist und in Abhangigkeit von der Orientierung das
Vorzeichen wechseln kann. Den hohen Hall-Koeffizienten kann man zur
Messung magnetischer Felder mit Hall-Sonden ausnutzen. Um den Ein
fluss einer abnehmenden Schichtdicke auf den Hall-Effekt zu
untersuchen, war es erwunscht, auch Messungen an einkristallinen
Schichten verschiedener Orien tierung durchzufuhren. Ein positives
Vorzeichen des Hall-Effektes ist zu erwarten, wenn die (lll)-Ebene
parallel zur Schicht liegt und das transversale Magnetfeld in
Richtung der trigonalen Achse zeigt. Derartig orientierte Schichten
konnten durch Epitaxie auf Glimmer-Spaltflachen erhalten werden."
