A Study of Growth Processes in Germanium Dendrites Using Pulse Electroplating Techniques

Abstract

Pulse electroplating is shown to reveal resistivity variations in g e r m a n i u m dendrites. The evolution of the edges of the dendrites is deduced from the configuration of the resistivity variations. The results suggest that dendritic growth involves at least two processes.

Electrodeposition of chromium with periodic reverse and pulsed current

“…Initial experiments showed much less differential between edge and center deposit thickness than expected using parallel electrodes so the first group of PR tests were made with the cathode at an angle of [30][31][32][33][34][35] degrees to the anode to accentuate distribution disparity. The closest edge was one-fourth inch from the anode.…”
