论文摘要
他的原子散射已被证明是对金属和金属层面表面上电子相互作用参数$λ$的敏感探针。这里表明，将$λ$与原子散射光谱的热衰减联系起来的理论（Debye-Waller因子）可以应用于拓扑半学表面，例如准二维电荷密度密度波系统BI（114）和分层的pnict pnictogen chalcogenides。
He atom scattering has been demonstrated to be a sensitive probe of the electron-phonon interaction parameter $λ$ at metal and metal-overlayer surfaces. Here it is shown that the theory linking $λ$ to the thermal attenuation of atom scattering spectra (the Debye-Waller factor), can be applied to topological semimetal surfaces, like the quasi-one dimensional charge-density-wave system Bi(114) and the layered pnictogen chalcogenides.
