Nanoanalysis of Interreactions

Interreaction of Ag/Al thin films

The reaction of nano-crystalline thin films was analysed by atomprobe tomography. Due to the real three-dimensional volume reconstruction of this method, it gets possible to determine atomic transport even in systems with the complex morphology induced by a grain size of about 5 nm diameter. The predominant transport along the grain boundaries of Ag was shown. Nucleated at the grain boundaries, an Al-rich grain boundary phase forms, that was previously unknown.
