Electron holography at medium resolution simultaneously probes projected electrostatic and
magnetostatic potentials as well as elastic and inelastic attenuation coefficients with a
spatial resolution of a few nanometers. In this work, we derive how the elastic and inelastic
attenuation can be disentangled. Using that result, we perform the first three dimensional
tomographic reconstruction of potential and (in) elastic attenuation in parallel. The technique
can be applied to distinguish between functional potentials and composition changes in …
