Supplementary Data for Chuyi Ni PhD Thesis 'Synthesis of High-Entropy Germanides and Investigation of the Formation Process'

The videos were collected at the same time as the in situ heating scanning transmission electron microscopy experiments. TEM samples were prepared by depositing a drop (5 μL) of a dilute ethanol suspension of metal salts and GeNSs onto a DENSsolutions Wildfire Si3N4 nano-chip.

The heating program was monitored by DENSsolutions Impulse software. After collecting the images and EDX mapping at room temperature, the samples were heated up to 800 °C at 1 °C/s and kept at 800 °C for 10 min. Then the samples were cooled down to room temperature at 20 °C/s.
