Abstract
Two-dimensional antimonene with a honeycomb structure has attracted significant attention in recent years due to its novel properties and tunable electronic structure as varying applied in-plane strain. Yet, applying epitaxially strained antimonene is greatly limited by the strong coupling with the metal substrates. Here, we demonstrate the synthesis of the van der Waals stretched antimonene on graphene/Cu(111) substrate via remote epitaxy. It is found that, as corroborated by atomic force microscopy and reflection high-energy electron diffraction, the lattice of the antimonene can be remotely stretched by the underlying Cu(111). The graphene layer prevents antimonene from forming the surface alloy with Cu(111), which is also confirmed by Raman spectroscopy results. Our study not only provides a way to regulate the lattice of the epitaxial layers remotely but also provides a new idea for developing new potential topological materials.
期刊介绍:
Surface Science is devoted to elucidating the fundamental aspects of chemistry and physics occurring at a wide range of surfaces and interfaces and to disseminating this knowledge fast. The journal welcomes a broad spectrum of topics, including but not limited to:
• model systems (e.g. in Ultra High Vacuum) under well-controlled reactive conditions
• nanoscale science and engineering, including manipulation of matter at the atomic/molecular scale and assembly phenomena
• reactivity of surfaces as related to various applied areas including heterogeneous catalysis, chemistry at electrified interfaces, and semiconductors functionalization
• phenomena at interfaces relevant to energy storage and conversion, and fuels production and utilization
• surface reactivity for environmental protection and pollution remediation
• interactions at surfaces of soft matter, including polymers and biomaterials.
Both experimental and theoretical work, including modeling, is within the scope of the journal. Work published in Surface Science reaches a wide readership, from chemistry and physics to biology and materials science and engineering, providing an excellent forum for cross-fertilization of ideas and broad dissemination of scientific discoveries.
