Fig. 6 Morphology and crystallinity of borophene-graphene heterostructures: (a~c) SEM images of few-layer graphene, borophene, and borophene-graphene heterostructure; (d) Low-resolution TEM image of a typical borophene-graphene heterostructure; (e) Low-resolution TEM image of borophene; (f) HRTEM image extracted from the green rectangular region in (e). Insets show the corresponding SAED patterns and HRTEM images obtained from computational models; (g~i) STEM-HAADF-EDS elemental mapping of the borophene-graphene heterostructure[85].
