The amplitude of sidebranches in the dendritic crystal growth of
ammonium chloride
   [PDF]

Andrew Dougherty
We report new measurements for the amplitude of sidebranches in the dendritic crystal growth of ammonium chloride from supersaturated aqueous solutions. No simple power law is found to describe either the growth of the average sidebranch amplitude or the average sidebranch envelope. Instead, the effective power law exponent appears to increase as a function of distance from the dendritic tip. We also find that the amplitude of the sidebranches in this system is significantly larger than predicted by models of noise-driven sidebranching.
