Improved Three-Dimensional Reconstructions in Electron Ptychography through Defocus Series Measurements
Marcel Schloz, Thomas C. Pekin, Hamish G. Brown +9
A detailed analysis of ptychography for 3D phase reconstructions of thick specimens is performed. We introduce multi-focus ptychography, which incorporates a 4D-STEM defocus series…

Relative roles of multiple scattering and Fresnel diffraction in the imaging of small molecules using electrons, Part II: Differential Holographic Tomography
T. E. Gureyev, H. M. Quiney, A. Kozlov +3
It has been argued that in atomic-resolution transmission electron microscopy (TEM) of sparse weakly scattering structures, such as small biological molecules, multiple electron sc…
