Abstract

Metal/ceramic interfaces have become important for advanced technologies in a variety of ways. To effectively tailor their properties, it is important to understand the mechanisms which govern the structural formation of the systems during deposition or post-deposition processing. Here, results on epitaxial re-crystallization of the Ni/MgO(0 0 1) interfaces are reported: (i) as deposited, the Ni films were grown on the MgO(0 0 1) substrates epitaxially, (ii) consecutive thermal annealing incited the process of re-crystallization, which led to the substantial improvement of their crystalline quality. The restructuring proceeded in a non-linear way, indicating that an intricate structural evolution was triggered in the system. Based on the results of the X-ray diffraction and Rutherford backscattering/channeling, the effect of thermal processing on the structural transformation of the Ni/MgO(0 0 1) interface is discussed in this paper.
