Figure 2: Slab-based band-structure calculations.
From: Interplay of Dirac fermions and heavy quasiparticles in solids
Respective computations were performed for a surface covered by (a) Si and (b) Eu atoms. The maroon-shaded area corresponds to the surface-projected bulk band structure, whereas the grey lines are the result of a calculation for a slab model. The green (blue) dots scale with ratio of localization: if the charge density is mainly located at the surface, then the size of the respective dot is at its maximum, whereas for equally distributed charge density, it vanishes.
