Two-dimensional (2D) antimony (Sb, “antimonene”) is of interest in electronics and batteries. Sb however exhibits a large allotropic structural diversity, which is also influenced by its support. Thus, Sb heterostructure formation is key in 2D Sb integration. Particularly, 2D Sb/graphene interfaces are important. We thus study here few-layered 2D Sb/graphene heterostructures with atomic resolution (scanning) transmission electron microscopy. We find two Sb morphologies to coexist: first, a 2D morphology of layered β-Sb with β-Sb(001)||graphene(001) texture. Second, one-dimensional Sb nanowires which can be matched to β-Sb[2-21]⊥graphene(001) and are closely related to cubic Sb(001)||graphene(001). Importantly, both Sb morphologies show rotational van-der-Waals epitaxy with graphene. Both are resilient against oxidation, although superficial Sb-oxide formation merits consideration, including epitaxial Sb₂O₃(111)/β-Sb(001) heterostructures. Exact Sb growth behavior depends on processing and substrate properties including, notably, the support underneath the graphene. Our work elucidates the rich phase and epitaxy landscape in 2D Sb and 2D Sb/graphene heterostructures.

二维（2D）锑（Sb，“锑烯”）在电子产品和电池中引起关注。然而，Sb表现出较大的同素异形结构多样性，这也受到其支持的影响。因此，Sb异质结构的形成是2D Sb集成的关键。特别地，2D Sb /石墨烯界面很重要。因此，我们在这里用原子分辨率（扫描）透射电子显微镜研究了几层2D Sb /石墨烯异质结构。我们发现两种Sb形态可以共存：首先是具有β-Sb（001）||石墨烯（001）织构的分层β-Sb的2D形态。第二，这可匹配一维的Sb纳米线β-Sb的[2-21] ⊥石墨烯（001）与立方Sb（001）||石墨烯（001）密切相关。重要的是，两种Sb形态都显示出旋转范德华与石墨烯的外延。两者都具有抗氧化的能力，尽管表面Sb-氧化物的形成值得考虑，包括外延Sb ₂ O ₃（111）/β-Sb（001）异质结构。确切的Sb生长行为取决于工艺和基材特性，尤其包括石墨烯下方的载体。我们的工作阐明了2D Sb和2D Sb /石墨烯异质结构中的富相和外延景观。
