Abstract
We investigate morphological evolution of Ar+ ion sputtered Pd(001) by in situ real‐time x‐ray reflectivity and grazing incidence small angle x‐ray scattering (GISAXS) experiments. Surface roughness W, and its dynamic scaling behavior show a definite crossover across a crossover time tc. Before tc, growth exponent β, varies from 0.20 to 0.49 depending on substrate temperature, T. After tc, β drops to ∼0.1, irrespective to substrate temperature. Satellite peaks in GISAXS indicating laterally ordered structure develop as the growth time approaches tc, which become clear with further sputtering. We think that the crossover behavior near tc indicates the reduction of non‐linear effect and the scaling behavior would follow the Edwards‐Wilkinson model.
