A glimpse inside the atom

Using electron microscopes, it is possible to image individual atoms. Scientists at TU Wien have calculated how it is possible to look inside the atom to image individual electron orbitals. An electron microscope can't just snap a photo like a mobile phone camera can. The ability of an electron microscope to image a structure - and how successful this imaging will be - depends on how well you understand the structure. Complex physics calculations are often needed to make full use of the potential of electron microscopy. An international research team led by TU Wien's Prof. Peter Schattschneider set out to analyse the opportunities offered by EFTEM, that is energy-filtered transmission electron microscopy. The team demonstrated numerically that under certain conditions, it is possible to obtain clear images of the orbital of each individual electron within an atom.
