Superroughening versus intrinsic anomalous scaling of surfaces (original) (raw)
2000
We study kinetically rough surfaces which display anomalous scaling in local properties such as the rough- ness or the height-difference correlation function. By studying the power spectrum of the surface and its relation to the height-difference correlation, we distinguish two independent causes for anomalous scaling. One is superroughening ~global roughness exponent larger than or equal to 1!, even if the
