The dynamics of “heat and pull” was directly visualized with nanometre precision in real-time, exemplifying in-situ observations of micro and nanoscale light-matter interactions.

Although electrons usually move in three dimensions, scientists can force electrons to move in two dimensions (2D) by creating ultra-thin materials.
