Photoemission from Ouantum Weil (QW)
Simple one-dimensional (1D) model assumes finite potential well with thickness given by integer number of Pb(111) crystal monoatomic layers (ML).
r
Depth of the well, Fermi energy position and electron effective mass are taken from much morę advanced calculations within pseudopotential model of the band structure (J. R. Anderson and A. v. Gold, Phys. Rev. 139, A1459 (1965)).
Following images show examples of ARPES results for photoelectrons with momentum component along F -M direction of the surface Brillouin Zonę ([112] direction in the real space).
