“…Snapshots of the growing film in Fig. 1 reveal the development of disordered "mounds" [3,4] It is straightforward to show that [15] C(qi,~) = n exP[iqi j]P~~, and below we set AC(q&, B4) = C(qi, BZ) -C (q i,~) . Near q = 0, the intensity decomposes into Bragg delta function a-nd diffuse components, as [2) I(q, q ) = (2') A "(q)B(q) + I, (q, q ), (2) where AB"ss(qi) = C(qi,~) and I&;«(q, q~) = (3) where the~, are the cumulants of f (~i = 0 and K2 = 1).…”
