In this letter, we report the branched fractal patterns (BFP) of
binary semiconductors (
and 
) by
electrochemical deposition. Clear fractals are observed for
, whereas fractals with scattered grains are observed
for . The higher the current density the more favorable
the formation of BFP, whereas low current density favors the
growth of scattered grains. This suggests the growth of
by two different mechanisms and is supported by the bimodal size
distributions observed for samples that show BFP with scattered
grains. The BFP of and are discussed on the
basis of the multiparticle Monte Carlo model described in the
literature.
