[EN] The growth kinetics of ZnO nanorods were studied by means of an electrochemical deposition process on ITO electrodes submerged in an aqueous solution of 5 mM ZCl + 0.1 M KCl at 80 degrees C. The stages of the growth kinetics showed a mechanism of formation of nano-spheres which with time were transformed into hexagonal crystals of ZnO. Cathodic current densities of 0.1 to 1 mAcm(2) formed hexagonal columns of 800 nm thickness while stronger currents formed a high-density layer of cylindrical nanorods 80 nm in diameter. An amorphous barrier layer was found between the surface of the electrode and the base of the nano-columns. The conditions assayed showed the possibility of adjusting the morphological characteristics of the layer in order to obtain different properties in different applications.
