Samples of low- medium- and high-entropy sulfides were annealed at high pressure and ambient temperature to explore the entropic stabilisation. Pre- and post-annealing samples were analysed by 4D-STEM (scanning electron diffraction) and STEM-EDX to explore the changes in the nanscale distribution of elements and phases.

Pre-annealed STEM-EDX data is in "0005 - SI HAADF 4000 x Nano.emd"

Pre-annealed 4D-STEM data is in scan1.blo, scan2.blo, scan3.blo and scan4.blo

Post-annealed STEM-EDX data is in "SI HAADF 1604 32000 x.emd" and "SI HAADF 1552 46000 x.emd"

Post-annealed 4D-STEM data is in "annealed-region3.blo" and "annealed-region4.blo"

A python notebook explaining how to open and interact with the EDX data is provided. Also a python notebook to open and interact with the 4D-STEM data is provided.
