The seeder of the pack : The electrical potential distribution (see phase image of an electron hologram) around the basal plane close to the prism faces of a hexagonal fluorapatite–gelatine nanocomposite seed influences the growth of the nanocomposite. The seed consists of elementary dipoles on the nanometer scale, which all have the same orientation along the c axis of the composite seed. Further form development of the seed leads to fractal patterns.
