Abstract
The growth of Fe on a clean Be(0001) surface is investigated on the atomic scale by a combined scanning tunneling microscopy and density functional theory study. At low Fe coverage, the nucleation of terraced nanoislands with a disordered surface is observed experimentally. Increasing the Fe coverage results in the growth of extended films exhibiting a well-ordered p superstructure. Density functional theory is applied to investigate the growth of Fe on a Be(0001) surface from individual atoms to extended films. Our studies provide strong evidence for the formation of a buckled honeycomb Fe lattice that is embedded in two Be planes with Kagome and triangular symmetry, respectively.
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.
