Randomly oriented twin domains in electrodeposited silver dendrites
Abstract
Silver dendrites were prepared by electrochemical deposition. The structures of the Ag dendrites, the type of twins and their distribution were investigated by scanning electron microscopy (SEM), Z-contrast high angle annular dark field transmission electron microscopy (HAADF), and crystallographically sensitive orientation imaging microscopy (OIM). The results revealed that the silver dendrites were characterized by the presence of randomly distributed 180 degrees rotational twin domains. The broad surface of dendrites was of the {111} type. The directions of growth of the main dendrite stem and all branches were of the LT 112> type.
