Abstract We extend the diffusion-limited aggregation model of Witten and Sander to the electrochemical deposition system by considering the effects of the external electric field. A jump probability for field-biased-diffusion is reasonably deduced, which enables us to obtain a series of loopless random fractals with varying fractal dimensions.
