Image processing in the material science or fractal behaviour on the GaAs/electrolyte interface

Here, pattern formation on GaAs (001) surface after electrochemical layer removal with the help of image processing was investigated. The morphology of GaAs surface shown fractal behaviour under non-selective etching conditions. The morphological surface study was carried out using digital image processing of scanning electron microscope data. The surface patterns were segmented by the so called grade of membership method. Fractal properties were established using the box counting method.
