The influence of tartaric acid on the growth kinetics of silver single crystals

Abstract The influence of tartaric acid (TA) on both the growth kinetics and morphology of silver single crystals was investigated in situ during electrocrystallization. Using laser interferometry the dependence of the monoatomic step velocity vs. overvoltage at different concentrations of TA was studied. Measuring the normal growth rate R we calculated the current on the front crystal face. It is shown that the addition of TA changes its value in complicated way vs. overvoltage.
