I have measured the early stages of the growth of branched metal aggregates formed by electrochemical deposition in very thin layers. The growth rate of spatial Fourier modes is described qualitatively by the results of a linear stability analysis [D.P. Barkey, R.H. Muller, and C.W. Tobias, J. Electrochem. Soc. 136, 2207 (1989)]. The maximum growth rate is proportional to ((I)/(c))^\ensuremathδ where I is the current through the electrochemical cell, c the electrolyte concentration, and \ensuremathδ=1.37\ifmmode±\else\textpm\fi0.08. Differences between my results and the theoretical predictions suggest that electroconvection in the electrolyte has an influence on the instability leading to ramified growth.
