Instability-Driven Streak Formation During Convective Deposition

The formation of streaks, often unwanted localized multilayer particle deposition oriented in the direction of deposition, is studied across a robust variety of process conditions.  In systems where streaks form, many streaks are initiated and then coarsen and merge as the deposition progresses.  Image analysis of streaks give a detailed account of their formation and development.  Insights into the formation of this stochastic process will be given and suggest ways to suppress the formation of streaks.
