English: Surface density of atoms according to the orientation of the face, in case of a monoatomic simple cubic crystal.
The bottom right part of the picture represents the atoms seen from a side view; the broken line highlight the orientation of the free faces (100), (210) and (110). The three figures on the top represent views perpendicular to the free faces.
The atom density influences the surface tension and surface reactivity.
Français : Densité de surface des atomes d'un cristal selon l'orientation de la facette, pour un cristal monoatomique de structure cubique simple.
La figure représente en bas à droite les atomes d'un cristal vu de profil ; la ligne brisée surligne les orientations des faces libres (100), (210) et (110). Les trois figures en haut représentent les vues perpendiculaires aux faces.
La densité de surface détermine notamment la tension superficielle et la réactivité chimique de la surface.
