    Notizen: An amorphous Ge-Au(a-Ge-Au) film prepared by vacuum deposition was studied in situ and irradiated by an electron beam in a transmission electron microscope. The amorphous Ge-Au film can be crystallized rapidly and locally by electron beam irradiation, forming polycrystalline metastable Ge0.4Au0.6 tetragonal phase and then decomposing to polycrystalline Ge and polycrystalline Au at increased irradiation dose. The results suggest that the crystallization of a-GeAu film, the formation of Ge0.4Au0.6 and the decomposition of the metastable Ge0.4Au0.6 are dependent on the temperature rise of the irradiation process. © 1996 American Institute of Physics.

    Fractals in annealed Ge-Au/Au bilayer films (1995)

    Notizen: Ge-22 at. %Au/Au bilayer films annealed at various temperatures have been observed by transmission electron microscopy. The as-deposited bilayer film is composed of crystalline Ge,Au and metastable Ge0.4Au0.6 phases. The Au grain size is nonuniform, and no amorphous Ge is observed. During annealing at 60–350 °C, patterns with several wide branches are generated that are different from the dense branching fractals induced by crystallization of amorphous Ge in a-Ge/Au films. The fractal dimension of the pattern (measured by the box-counting method) increases with the annealing temperature. The agglomeration of small Au grains to coarse Au grains in the Ge-Au/Au bilayer film may be the mechanism for the fractal structure formation. © 1995 American Institute of Physics.
