Structures in Ultrathin Films

Mention was made of polycrystalline aggregate growth near free surfaces (Fig. 3.42) or confined surfaces (Fig. 

A discussion of Unear growth rates is the subject of Chapter 6 nevertheless, one is struck here by the reduction of G that sets in when the thickness d of the free 

Mareau and Prud homme. Multilayer structures grown at room temperature in films with d 100 nm, best described as poorly faceted hedrites, exhibit single crystal texture by ED [70]. The inescapable conclusion is that, at least in thin and ultrathin films, the growth direction of, or within, a single crystal can occur in a manner that bears no relation to crystal symmetry.
