“…33 Meanwhile, Shi et al showed that the distorted hexagonal-like Sb lattice formed on the SnSe substrate at the initial stage will eventually transform into the energetically favorable α-Sb. 34 As the surface structures and chemical compositions of WTe 2 , MoTe 2 , PdTe 2 , and Bi 2 Se 3 are rather similar, these behaviors suggest that there might be a competition between the αand β-phases when an antimonene sheet is epitaxially grown on a substrate and that the final structure of antimonene might be tuned by the substrate. However, a comprehensive understanding on the controllable growth of αand β-Sb by the choice of substrates is still missing, which should be vital for the preparation and practical applications of antimonene and analogues.…”

Antimonene has two different allotropes, namely, orthorhombic α-Sb and rhombohedral β-Sb. Both phases exhibit unique electronic properties and have been prepared on various substrates. However, the controllable growth of α- and β-Sb has remained challenging. In the present work, we demonstrate that α- and β-Sb can be controllably grown on a family of inert substrates with hexagonal structures. The preferential phase of antimonene can be tuned through the interfacial strain induced by the lattice mismatch. Our work clarifies the mechanism for the controllable growth of α- and β-Sb on various substrates, shedding light on the synthesis of 2D Xenes suitable for practical applications.

“…In analogy to other elemental 2D materials, phase engineering can be realized via delicately tuning the substrate temperature and using appropriate substrates. − Black-phosphorus like antimonene can be stabilized on Bi 2 Se 3 after room temperature (RT) deposition, and transforms to blue-phosphorus like phase after annealing at 473 K due to the perfect lattice match . The phase transition of 2D materials from puckered to buckled phase has shown to be a general trend via bond breaking pathway when taking into the substrate into account.…”

Binary two-dimensional (2D) materials comprising main group elements with several phases of AB and AB2 stoichiometry provide significantly rich physics and application potentials. We present the epitaxial growth of two phases of atomically thin SnSb on a Cu2Sb surface alloy under ultrahigh-vacuum (UHV) conditions. Theoretical studies predict that these 2D SnSb sheets adopt the atomic configurations similar to those of black and blue phosphorene but with Sb–Sn–Sn–Sb motif (R- and H-phases) holding an indirect band gap of 0.20 and 0.85 eV, respectively. Our low-temperature (77 K) scanning tunneling microscopy characterizations, and first-principles theoretical calculations, reveal the atomic structures and semiconducting properties of the most stable H-phase, displaying a commensurate lattice growth mode on Cu2Sb(111) but a weak interfacial interaction. Strain-engineered band gap, effective mass, and Young’s Modulus of the most stable H-phase are further explored theoretically. These results suggest that 2D SnSb with intriguing properties has great potential for electronics in an atomically thin platform.

Graphene, as the representative of two-dimensional materials, has varous novel physical properties and potential applications. The intrinsic zero band gap of graphene limits its application in semiconductor devices, and thus the search for new semiconducting alternative materials has become a current research hotspot. Phosphorene is the monolayer of black phosphorus and has a puckered honeycomb structure. Its advanced properties, such as adjustable direct band gap, high carrier mobility and in-plane anisotropy and so on, have recently aroused great research interest, thus opening up the research field of puckered honeycomb monolayers in group V elements. In this article, we first focus on the structure, synthesis and physical properties of five single-element two-dimensional materials (nitrogen, phosphorus, arsenic, antimony and bismuth) each with puckered honeycomb structure. Second, some binary two-dimensional materials with puckered honeycomb structure are discussed, including IV-VI and V-V compounds. These materials have their own unique crystal symmetry, and the properties can be controlled by changing their structures and dimensions. Finally, we also make a summary on some current challenges that need to be solved, and the possible future applications of these two-dimensional materials are also presented.
