- W2121620900 abstract "We have performed angle-resolved photoemission and core-level x-ray photoemission studies of the single-layer cuprate ${mathrm{Bi}}_{2}{mathrm{Sr}}_{2ensuremath{-}x}{mathrm{La}}_{x}mathrm{Cu}{mathrm{O}}_{6+ensuremath{delta}}$ (Bi2201) and revealed the doping evolution of the electronic structure from the lightly doped to optimally doped regions. We have observed the formation of the dispersive quasiparticle band, evolution of the Fermi ``arc'' into the Fermi surface, and the shift of the chemical potential with hole doping as in other cuprates. The doping evolution in Bi2201 is similar to that in ${mathrm{Ca}}_{2ensuremath{-}x}{mathrm{Na}}_{x}mathrm{Cu}{mathrm{O}}_{2}{mathrm{Cl}}_{2}$ (Na-CCOC), where a rapid chemical potential shift toward the lower Hubbard band of the parent insulator has been observed, but is quite different from that in ${mathrm{La}}_{2ensuremath{-}x}{mathrm{Sr}}_{x}mathrm{Cu}{mathrm{O}}_{4}$ (LSCO), where the chemical potential does not shift, yet the dispersive band and the Fermi arc and/or surface are formed around the Fermi level already in the lightly doped region. The (underlying) Fermi surface shape and band dispersions are quantitatively analyzed using tight-binding fit, and the deduced next-nearest-neighbor hopping integral ${t}^{ensuremath{'}}$ also confirms the similarity to Na-CCOC and the difference from LSCO." @default.
