We apply high resolution x-ray diffraction to study the development of the c(2×2) phase of Pb on Ni(001). We observe lineshapes in agreement with the scaling theory of Ohta, Jasnow, and Kawasaki, but with an anomalously slow time dependence of average domain size R on time t, R α t0.12. The presence of 1%–3% carbon on the surface apparently acts as a weak random field.
