Lattice- vs. grain-boundary-controlled interdiffusion in BiSb bilayer films

Bi and Sb were deposited in a bilayer configuration with either Bi or Sb as the underlying layer. The morphology and structure of these films were very different depending on the deposition order. The films were annealed during in situ observation in a transmission electron microscope in order to study the changes caused by interdiffusion. Grain-bo oundary- or lattice-controlled interdiffusion processes were observed depending on the initial film microstructure.
