Ultrafast processes on nanoscale dimensions are at the heart of today’s high technology, including such diverse applications as the efficient harvesting of light induced carriers in photovoltaics or the heat management in dense semiconductor devices. Currently, however, we are urgently lacking the experimental toolbox to map such phenomena on their intrinsic femto- and picosecond timescales, and on nanometer length scales.Our group aims to develop novel ultrafast stroboscopic electron imaging approaches for the mapping of nanoscale dynamics in lattice, electron and spin degrees-of-freedom. As a central experimental tool, we apply here for funding for an ultrafast transmission electron microscope. Based on our previous developments in the field, we want to establish ultrafast transmission electron microscopy as a versatile methodology for the real-space imaging of nanoscale energy conversion and transfer processes.
