Compressive Electron Backscatter Diffraction Imaging

Autor: Broad, Zoë, Robinson, Alex W., Wells, Jack, Nicholls, Daniel, Moshtaghpour, Amirafshar, Kirkland, Angus I., Browning, Nigel D.

Electron backscatter diffraction (EBSD) has developed over the last few decades into a valuable crystallographic characterisation method for a wide range of sample types. Despite these advances, issues such as the complexity of sample preparation, re

The Potential of Subsampling and Inpainting for Fast Low-Dose Cryo FIB-SEM Imaging and Tomography

Autor: Nicholls, Daniel, Kobylysnka, Maryna, Wells, Jack, Broad, Zoe, Robinson, Alex W., McGrouther, Damien, Moshtaghpour, Amirafshar, Kirkland, Angus I., Fleck, Roland A., Browning, Nigel D.

Traditional image acquisition for cryo focused ion-beam scanning electron microscopy tomography often sees thousands of images being captured over a period of many hours, with immense data sets being produced. When imaging beam sensitive materials, t

Subsampling Methods for Fast Electron Backscattered Diffraction Analysis

Autor: Broad, Zoë, Nicholls, Daniel, Wells, Jack, Robinson, Alex W., Moshtaghpour, Amirafshar, Masters, Robert, Hughes, Louise, Browning, Nigel D.

Despite advancements in electron backscatter diffraction (EBSD) detector speeds, the acquisition rates of 4-Dimensional (4D) EBSD data, i.e., a collection of 2-dimensional (2D) diffraction maps for every position of a convergent electron probe on the

In silico Ptychography of Lithium-ion Cathode Materials from Subsampled 4-D STEM Data

Autor: Robinson, Alex W., Moshtaghpour, Amirafshar, Wells, Jack, Nicholls, Daniel, Broad, Zoe, Kirkland, Angus I., Mehdi, Beata L., Browning, Nigel D.

High quality scanning transmission electron microscopy (STEM) data acquisition and analysis has become increasingly important due to the commercial demand for investigating the properties of complex materials such as battery cathodes; however, multid
