论文摘要
原子散射已被公认为是金属和金属超层表面上电子相互作用参数$λ$的敏感探针。 Here, the theory is developed linking $λ$ to the thermal attenuation of atom scattering spectra (in particular, the Debye-Waller factor), to conducting materials of different dimensions, from quasi-one dimensional systems such as W(110):H(1$\times$1) and Bi(114), to quasi-two dimensional layered chalcogenides and high-dimensional surfaces such as准晶2ML-BA（0001）/CU（001）和D-Alnico（00001）。使用HE原子获得的$λ$的值与散装材料的已知值相比。相应的分析表明，除了在原子表面碰撞中测量的电子 - 光子相互作用的层数。
Atom scattering is becoming recognized as a sensitive probe of the electron-phonon interaction parameter $λ$ at metal and metal-overlayer surfaces. Here, the theory is developed linking $λ$ to the thermal attenuation of atom scattering spectra (in particular, the Debye-Waller factor), to conducting materials of different dimensions, from quasi-one dimensional systems such as W(110):H(1$\times$1) and Bi(114), to quasi-two dimensional layered chalcogenides and high-dimensional surfaces such as quasicrystalline 2ML-Ba(0001)/Cu(001) and d-AlNiCo(00001). Values of $λ$ obtained using He atoms compare favorably with known values for the bulk materials. The corresponding analysis indicates in addition the number of layers contributing to the electron-phonon interaction that is measured in an atom surface collision.
