Towards a holographic approach to spherical aberration correction in scanning transmission electron microscopy. [PDF]
Optics Express, 2017 Recent progress in phase modulation using nanofabricated electron holograms has demonstrated how the phase of an electron beam can be controlled. In this paper, we apply this concept to the correction of spherical aberration in a scanning transmission ...
