The increased adsorption strength of Hg0 on the defective Au(111) surface with 3 vacancies is attributed to the upward shift of the d-band center to Fermi level. The presence of S or O impurity atom weakens the interaction between Hg0 and Au surface [496], because the impurity atoms ...
(or +1 to −1 V on Au) and takes 2 min for the complete sweep. After two completed autonomous experiments, drift was measured to be on the order of 0.5 ± 0.2 Å on WS2and 1.1 ± 0.8 Å over Au{111} that is shown in Supplementary Fig.12. Hyperparameters can be...
However, we would note that in this work, the effect comes mainly from size rather than geometry because at least for ~3 and ~7 nm Au NPs the structure is same (truncated octahedron with Au {111} and {100} facets mainly exposed, Supplementary Fig. 11). Mechanism of the size-...
The patterns within the SFT have a very high intensity compared with that of the surrounding Au(111) surface up to the bottom of the bulk conduction band around 3.7 V (see Fig. 2d). Above this value, the signal on the Au(111) surface increases drastically and wave patterns of the SFT...
On the surface with Fe monatomic rows, photoemission spectra measured in the direction perpendicular to the steps show a parabolic dispersion of the Au(111) surface state with downward energy shift of the band bottom; the clean surface, in contrast, shows two 1D quantum-well levels. A simple ...
Surface structure, band structure and electrical conductance of Au and Na coadsorbed Si(111)√3×√3 reconstruction have been studied in situ with low-energy electron diffraction, scanning tunneling microscopy, angle-resolved photoelectron spectroscopy and four-point probe technique. The Si(111)-h-...
(111) substrate. Using scanning tunneling microscopy, X-ray spectroscopies, and theoretical calculations, we reveal the role of buried B species in forming the nanostructured Au layers. Changes in the Au monolayer’s band structure upon substrate decoupling indicate a transition from 3D to 2D metal...
