“…It is worth noting that this rumpling is inherent to the ffiffiffi 3 p X ffiffiffi 3 p R30 structure but its accurate value depends on the materials. For example, on Bi/Ag(111), a rumpling of 0.6 Å has been measured by LEED [22] and calculated by density functional theory [19]. Fig.…”

“…In the present case, the surface Debye temperature relevant for the data is rather low, not least because of the heavy Bi atoms in the alloy. 41,42 The imaginary part of the corresponding self-energy , which is equivalent to half of the inverse lifetime, can be written as…”

Strongly enhanced electron-phonon coupling in the Rashba-split state of the Bi/Ag(111) surface alloy

The electron-phonon coupling strength of the ( √ 3 × √ 3)R30 • Bi/Ag(111) surface alloy is investigated by temperature-dependent angle-resolved photoemission. The electron-phonon coupling strength for the Rashbasplit surface state, as expressed by the mass-enhancement parameter λ, is found to be of the order of 0.55 with little change over the investigated binding energy range between 200 and 700 meV. This coupling is much stronger than for the clean Ag(111) surface state or for bulk Ag. It is, however, not found to increase near the the top of the band, where the density of states has a singularity.

“…The semi-infinite Bi=Agð111Þ system comprises three regions: bulk, surface, and vacuum. The geometric relaxation at the surface has been adopted from computations with the VIENNA ab initio simulation package (VASP) [35] and is in agreement with low-energy electron diffraction measurements [36,37]. From the layer-diagonal part of the Korringa-Kohn-Rostoker Green function, we compute the layer-dependent spectral density, using a broadening of 0.025 eV typical for this kind of computation [20].…”

Ambiguity of Experimental Spin Information from States with Mixed Orbital Symmetries

et al. 2014

The spin texture of the unoccupied bands of the surface alloy Bi/Ag(111) is investigated with spin- and angle-resolved inverse photoemission and first-principles calculations. Surprisingly, the measured spin character does not always reflect the calculated spin texture of the bands. With the help of photoemission calculations within the one-step model, however, the discrepancy is traced back to the influence of the orbital symmetry of the respective states in combination with the experimental geometry. In particular, the calculations show that the spin texture of a surface band with mixed orbital symmetries may neither be recovered with s- nor p- nor unpolarized light. In general, spin information from direct or inverse photoemission experiments on electronic states with mixed orbital symmetries at spin-orbit-influenced surfaces has to be taken with a pinch of salt, while it remains reliable for states with pure symmetry.
