Spectroscopy and energy-filtered TEM imaging using low energy losses (< 50 eV) is a useful technique (e.g. for band-gap mapping) but offers relatively poor spatial resolution, due to delocalization of the inelastic scattering. We will consider how this delocalization can be calculated, measured and perhaps modelled with sufficient accuracy to allow a useful improvement in the spatial resolution.
