Abstract:
The systematic in situ transmission electron microscopy (TEM) analysis suggests three stepwise formation stages during the growth of MoW1-S2 hexagonal flakes, which are the initial assembly of precursors into vertical structures, subsequent transition into horizontal structures, and final surface relaxing and faceting into hexagonal flakes.
