This stretching causes the material’s electronic band structure to become flattened, dramatically changing its interactions and properties. In the specific case of the 2D-3D moiré hybrid, Yankowitz ...

Researchers report that it is possible to imbue graphite -- the bulk ... of these materials -- with their more complex 3D atomic structures -- should behave differently. Or so they thought.

Before (a) and after (c) 2D virtual slices of a sample of graphite exposed to the molten salt. Images (b) and (d) show 3D sections of the region highlighted by the yellow rectangle in (a) and (c).
