“…7 for the first time. On the other hand, adsorption of antimony on the (111) surface of fcc metals, Sb/Cu(111) [11][12][13][14] and Sb/Ag(111), [14][15][16] has been investigated with the use of several experimental methods. In particular, Vries et al 14 employed the X-ray diffraction structure analysis to investigate the p( √ 3 × √ 3)R30 • reconstructions of Sb/Cu(111) and Sb/Ag(111) surfaces.…”

“…Antimony atoms are incorporated as an impurity in the Cu substrates at less than the order of 1 ppm, and it is well-known that antimony in copper easily segregates to the surface by annealing [16][17][18]. The surface concentration of antimony was estimated to be 2.2 at% by XPS measurements.…”

“…Similar to other elements mentioned above, Sb also tends to form alloys with Cu, Ag, and Au at low coverage. The atomic structures and electronic properties of the (3 × 3)R30 Ag 2 Sb(111) [ 196 ] and Cu 2 Sb(111), [ 197 ] c(2 × 2) Cu 2 Sb(110), [ 198 ] and p(2 × 2) Cu 2 Sb(100) [ 199 ] have been investigated for decades. In 2018, two groups reported the growth of flat antimonene on the Ag(111) surface, showing an enlarged lattice constant of 5 Å.…”

“…Both Sb and Bi prefer to form surface alloys with Ag and Cu at low coverage. [ 197,199,222,225 ] In addition to the lattice mismatch, the interaction strength with substrates and the role of surface alloys should be discussed in depth. [ 12,226 ] Unlike Sb, Bi does not form an alloy on Au(111).…”
