Gap-free Information Transfer in 4D-STEM via Fusion of Complementary Scattering Channels
Shengbo You, Georgios Varnavides, Sagar Khavnekar +12
Linear phase-contrast scanning transmission electron microscopy (STEM) techniques compatible with high-throughput 4D-STEM acquisition are widely used to enhance phase contrast in w…
Beyond Contrast Transfer: Spectral SNR as a Dose-Aware Metric for STEM Phase Retrieval
Georgios Varnavides, Julie Marie Bekkevold, Stephanie M Ribet +3
The contrast transfer function (CTF) is widely used to evaluate phase retrieval methods in scanning transmission electron microscopy (STEM), including center-of-mass imaging, paral…
Relaxing Direct Ptychography Sampling Requirements via Parallax Imaging Insights
Georgios Varnavides, Julie Marie Bekkevold, Stephanie M Ribet +3
Direct ptychography enables the retrieval of information encoded in the phase of an electron wave passing through a thin sample by deconvolving the interference effects of a conver…
