摘要

最近发表的一篇论文[2D Materials, 8, 045033 (2021)]报道，通过在钯（111）晶体表面沉积碲并随后进行热退火，可以在超高真空中生长出单层钯碲。通过低能电子衍射强度（LEED-IV）结构分析，我们发现所获得的 3×3R30° 超结构实际上是 TePd2 表面合金。通过增加表面的 Te 含量在超高真空中生成 PdTe2 层的尝试并不成功。

Tellurization of Pd(111) revisited: Formation of a TePd2 surface alloy but no PdTe2 monolayer

In a recent publication [2D Materials, 8, 045033 (2021)], it was reported that the growth of a monolayer PdTe $_{2}$ in ultra-high vacuum could be achieved by deposition of tellurium on a palladium (111) crystal surface and subsequent thermal annealing. By means of low-energy electron diffraction intensity (LEED-IV) structural analysis, we show that the obtained $(\sqrt{3} \times \sqrt{3}) R30 °$ superstructure is in fact a TePd $_{2}$ surface alloy. Attempts to produce a PdTe $_{2}$ layer in ultra-high vacuum by increasing the Te content on the surface were not successful.

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.
