Atomic structure and orientation relations of interfaces between Ag and ZnO

This paper presents the results of investigations of Ag-ZnO interfaces, produced by internal oxidation of an Ag-Zn alloy. ZnO precipitates with the wurtzite structure were found exhibiting mainly one orientation relation with the Ag matrix. However, closely related ORs were found, rotated by small angles from that orientation relation. The atomic structures of several interfaces surrounding these precipitates were studied and compared using HRTEM. The paper concentrates on interfaces between low index facets of ZnO and vicinal planes of Ag. These interfaces clearly show relaxations. An interpretation of these relaxations in terms of dissociation of partial dislocations at the interface is put forward
