Multiple origins of extra electron diffractions in fcc metals

Diffuse intensities in the electron diffraction patterns of concentrated face-centered cubic solid solutions have been widely attributed to chemical short-range order, although this connection has been recently questioned. This article explores the many non-ordering origins of commonly reported features using a combination of experimental electron microscopy and multislice diffraction simulations, which suggest that diffuse intensities largely represent thermal and static displacement scattering. A number of observations may reflect additional contributions from planar defects, surface terminations incommensurate with bulk periodicity, or weaker dynamical effects., , , # Multiple origins of extra electron diffractions in fcc metals

## Description of the data and file structure

**experiment.zip** contains underlying images/data for experimental figures. Each subdirectory contains data associated with one figure (fig1, sup fig 2, etc.).

dm3 and dm4 are proprietary data formats from Gatan, which can be freely accessed using [py4DSTEM](https://py4dstem.readthedocs.io/en/latest/api/py4DSTEM.html).

h5oina is a proprietary data format from Oxford Instruments, which can also be freely accessed using Python ([instructions](https://www.oxinst.com/blogs/taking-advantage-of-the-h5oina-file-format-using-python)).

**notebooks.tar.gz** contains various IJulia *.ipynb* notebooks used for generation, analysis, and plotting.

Most simulation configurations were generated in *generating_arbitrary_orientations.ipynb* using a fluid collec...
