Investigation of tellurium electrocrystallization by EHD impedance technique
Abstract
Electrohydrodynamical impedance measurements were performed during tellurium electrodeposition and correlated to the morphology of the deposits as observed by SEM. In particular, when the current is under a pure mass transport control, microdendrites are formed with various shapes depending on experimental conditions. EHD diagrams are then characteristic of a non-uniformly accessible surface. The calculated dimensions of active zones are in agreement with the sizes of the observed dendrite bushes.
