WebApr 3, 2014 · The graphene islands at the early stage of growth on H-terminated Ge (110) surface were uniaxially aligned along the [ 1 ¯ 10] direction of the underlying Ge (110) surface ( Fig. 1B) and then grown to form uniform monolayer graphene on an entire growth substrate ( Fig. 1C and fig. S2). WebJan 15, 2024 · As multiple graphene islands start to grow simultaneously from uncountable seeds in the growth procedure, it is not easy to control the orientations of the graphene islands in the wafer-scale [19]. It took nearly a decade before Lee et al. reported a successful wafer-scale growth of single-crystalline graphene on hydrogen-terminated …
