Abstract: (2451 Views)
In this study, morphology of nano-structured surface is measured by image processing of AFM (atomic force microscopy) images using a developed code (in MATLAB environment). For determination of surface morphology two parameters ; RMS roughness and correlation length, are important. In this article a novel method is introduced in which distance distribution function of neighbor peaks around a peak are considered for calculating the surface parameters. This method works well for estimation of surface correlation length and can compete with common technique in which autocorrelation function is used.
