On their not so closed-packed surfaces [(110) FCC for instance] roughening may occur, depending on the nature of the element. 6 Special Cases of Vicinal Surfaces All the above developments apply to surfaces which at T = 0 K are flat or exhibit an isolated step. We have seen that in this case the step edge is rough at any temperature. If we now consider a vicinal surface which exhibits a periodic succession of steps and terraces (Sect. 4), the preceding result is no longer valid since the steps interact and this should be included in the theory.

Schematic diagrams of surface surstructures. The adsorbates are indicated by circles and the surface atoms by points. The unit cells of both lattices are indicated, d is the bulk lattice parameter the substrate unit cell or when the ratio of the dimensions of these cells is not an integer. For simple rotations, (x x y) RO means a surface structure which is obtained from the surface unit cell by a rotation of angle 0, the length ofthe basis vectors being multiplied by x and y.

25]. An example is given in Fig. 15 showing the change of the morphology oflead crystals as a function ofthe growth temperature. This element has a FCC structure and at low temperatures (:$ 323 K) the crystal is bound by (111), (001), (110), (112) facets. Then, for 323 K < T < 393 K the (112) facets have disappeared. Finally, above 393 K and up to the melting point the only remaining facets are (111) and (001) which, being the most closed-packed, have the highest 42 2.
