  Epitaxial films of heavy fermion CeCu2Ge2 and CeFe2Ge2 are grown on DyScO3
and MgO substrates using molecular beam epitaxy. The growth begins via island
nucleation leading to a granular morphology. The grains grow flat with c-axis
orientation after nucleating, as indicated by in-situ reflection high energy
electron diffraction (RHEED) and ex-situ analysis including atomic force
microscopy (AFM) and x-ray diffraction (XRD). These single phase films show
similar temperature dependent transport to single crystals of the materials
indicating that similar collective order occurs in the films as in single
crystals.
