Fig. 2: Angle-resolved photoemission spectroscopy (ARPES) measurements of the nitrogene-like structure on Ag(100).
From: Evidence of a two-dimensional nitrogen crystalline structure on silver surfaces
a–e Constant energy contours (CECs) at binding energies of 1.4, 1.8, 2.2, 2.6, and 2.8 eV, respectively. The black and red dashed lines indicate the first Brillouin zones (BZs) of Ag(100) and the nitrogene-like structure, respectively. The \(\bar{{{{\rm{X}}}}}\) point of Ag(100) coincides with the M point of the nitrogene-like structure. f–j CECs of pristine Ag(100) at the same binding energies as panels (a–e). k–p ARPES intensity plots along Cuts 1-3 and 1’-3’, as marked in (a, f). Cuts 1-3 correspond to the nitrogene-like structure on Ag(100), while Cuts 1’-3’ correspond to pristine Ag(100). All CECs and cuts are presented as second-derivative images.
