Pulsed Electrodeposition of Tree-Like Copper Aggregates

Abstract

AbstractUsing pulsating current technique, we have been able to grow self-sustained, tree-like copper aggregates with a length of a few mm. The size of these aggregates allowed us to perform impedance and scanning electron microscope analysis. The morphology of the aggregates is found to be more compact than for deposits obtained in fixed-current dc conditions. However, their structure is still very irregular, and depends on the parameters characterizing the pulse sequence.
