Dynamic renormalization-group approach to growing surfaces with point-defects

The dynamic scaling properties of growing surfaces with point-defects have been studied by applying a dynamic renormalization-group approach to the generalized KPZ equation, which contains a growth inhomogeneity term of delta function. It can be shown, from the roughness exponent χ and dynamic exponent z obtained, that surface point-defects tend to roughen a growing surface and shorten its dynamic relaxation process to steady-growth state.
