Analysis of the Ordered Crystal Structure of Cu3Ge Intermetallic

Technical Note


We report the observation of metastable cubic phase with L12 superlattice in thin films of Cu3Ge. It is shown that the equilibrium ordered phase with orthorhombic D0a superlattice is formed directly from the L12 superlattice. If the atomic order is ignored, the transformation corresponds to the well-known face-centered cubic to hexagonal close-packed transformation.
