Abstract: The growth and shape evolution of epitaxial Fe 13Ge 8 (hexagonal lattice) islands on single crystal Ge(001) (cubic lattice) substrate was observed in real time using an in situ ultra-high vacuum transmission electron microscope (TEM). Post-deposition high-resolution TEM in conjunction with stereographic projection enabled the identification of the interface structure between the Fe 13Ge 8 islands and the Ge substrate. Only one low-energy coherent interface formed via Fe 13Ge 8 islands growing into the substrate along the inclined Ge(111) plane. This indicates that minimization of net interfacial energy is the driving force for hexagonal Fe 13Ge 8 islands formation on Ge(001). © 2012 Elsevier Ltd.
