Scalable characterization of 2D Gallium (2D Ga) heterostructure. (a) lowmagnification SEM image coverages a ~ 2 mm wide area. (b) and (c) are medium magnification SEM images of the 2D Ga surface and the corresponding segmentation. (d) and (e) are a close-up view from (b) and (c), respectively. Segmentation and coverage calculations are performed on a (5x6) image-matrix that covers all the white box in (a) with a total area of 1.5 mm x 2 mm.

... Furthermore, preliminary results of SEM contrast for other 2D metals and 2D alloys intercalated at the SiC/EG interface are found to be similarly reproducible, as illustrated in Figure S21 for 2D indium 53 and 2D indium gallium alloy. 7 The reproducibility of the SE suppression in SEM contrast is primarily controlled by the delamination of the BL, which acts as an extra potential barrier in front of the SE emission, regardless of the type of intercalant. ...
