Modulating Epitaxial Atomic Structure of Antimonene through Interface Design

Antimonene, a new semiconductor with fundamental bandgap and desirable stability, has been experimentally realized recently. However, epitaxial growth of wafer‐scale single‐crystalline monolayer antimonene preserving its buckled configuration remains a daunting challenge. Here, Cu(111) and Cu(110) are chosen as the substrates to fabricate high‐quality, single‐crystalline antimonene via molecular beam epitaxy (MBE). Surface alloys form...
