Klaus Heinemann
After completion of his Ph.D. thesis in applied physics at the
University of Tubingen, Germany, Klaus worked as an R&D
engineer at Siemens AG, Berlin, in the development of the Elmiskop
101 transmission electron microscope.
In 1969, he joined NASA-Ames Research Center as a National
Research Council Postdoctoral Research Fellow and worked on high
resolution TEM applications. For his development of dark-field
microscopy with annular objective apertures he received the 1972 NASA
Exceptional Scientific Achievement Award.
His research emphasis then shifted to surface physics with
high-resolution in-situ TEM investigations, including in-situ
oxidation and gas reaction studies under controlled (ultra-high)
vacuum conditions.
Major scientific milestones (published in over 60 peer-reviewed
articles in scientific journals) include revealing of the
(atomic-scale) thickness-dimensions of nanometer-size crystalline
particles, building of a 10(-8) Pa high-resolution TEM specimen
handling and reaction chamber, and the detection, characterization
and size classification of metal clusters consisting of just a few
atoms on amorphous substrates.
