Extended Data Fig. 6: SAED patterns taken from randomly picked 20 positions across the entire Bi film.
From: Realization of 2D metals at the ångström thickness limit
The diffraction area is ~1 μm, and adjacent SAED patterns are taken more than 5 μm apart. It can be seen that these SAED patterns are essentially identical with a degree of rotational misalignment <1°, evidencing the single-crystalline nature of the achieved monolayer Bi.
