Self-affine fractals and the limitH→0

Abstract
A modified form for the surface-height-fluctuation correlation function of rough surfaces, gγ(R)∝Fa0/ξR/ξ x2H (ex/x)dx, is investigated which depicts behavior related to self-affine fractals for 0<H<1, and for H→0 with a0R≪ξ reveals logarithmic behavior gγ(R)∝ln(R/a0).
