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 Professor Peter Schattschneider from the Vienna University of Technology set out to analyse the opportunities offered by energy-filtered transmission electron microscopy (EFTEM). The team demonstrated numerically that under certain conditions, it is possible to obtain clearimages of the orbital of each individual electron within an atom. Electron microscopy can therefore be used to penetrate down to the subatomic level - experiments in this area are already planned. The study has now been published in Physical Review Letters (doi: 10.1103/ PhysRevLett.117.036801).
