摘要

我们研究了三种不同吸附剂 Si、Be 和 P 在 (101¯0) Re 面上的高温联合吸附。在联合吸附过程中，其中一种吸附剂被转移到体液中，进入溶解状态。位移以原子到原子的方式发生，具有 "循环性质"：硅位移到磷，铍位移到硅，磷位移到铍。

Competition between silicon, beryllium and phosphorus atoms in the formation of surface chemical compounds on (101¯0) Re

High-temperature joint adsorption has been studied of three different adsorbates, Si, Be, and P on the $(10 \bar{1} 0)$ Re face. All three adsorbates form surface compounds with the stoichiometry ReX, where X is Si, Be, and P. In joint adsorption, one of the adsorbates is displaced into the bulk, into the dissolved state. The processes are observed at a temperature sufficient for diffusion in the bulk, 1100–1300 K. Displacement occurs in an atom-to-atom mode, and it has a “cyclic nature”: silicon displaces phosphorus, beryllium displaces silicon, and phosphorus - beryllium.

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.
