Epitaxial Mn(5)Ge(3) nano-islands on a Ge(001) surface.

چکیده
The growth behavior and atomic structure of Mn germanide, grown on Ge(001), is studied with x-ray diffraction and scanning probe microscopy. The amorphous clusters of as-deposited Mn are crystallized into Mn(5)Ge(3) nano-islands with a size of ∼100 nm by solid phase epitaxy. At low coverage, the shape of the nano-islands is plateau-like, while at increased coverage it becomes mound-like. At the flat top of the plateau-like nano-islands, the hexagonal atomic structure is resolved. It is interpreted, with the help of first-principles study, as a Mn-terminated Mn(5)Ge(3)(0001) structure.

Cobalt was deposited on single-crystal Ges001d surface at ,350 °C by electron-beam evaporation in an ultrahigh-vacuum transmission electron microscope. The deposited Co reacts with Ge to form nanosized islands with the cobalt germanide Co5Ge7 phase. The Co5Ge7 islands show square and rectangular shapes. Two epitaxial orientation relationships between Co5Ge7 and Ge were observed: Co5Ge7 k110ls00...

The formation of nano-islands on both a Ge(111)-c(2 × 8) surface and an Ag/Ge(111)-(√3 × √3) surface evaporated with 0.1 ML Ni was investigated by scanning tunneling microscopy (STM). We have noticed that at temperatures lower than 670 K, the reaction between Ni and the individual substrate surfaces proceeds to form different structures: flat-topped islands with a 2√7 × 2√7 or a 3 × 3 reconstru...
متن کاملIn-situ TEM study of low dimensional structures at kinetically constrained and equilibrium growth regimes
The structural and morphological evolution of low dimensional Fe-Ge structures (i.e. 0D/1D) during the reactive deposition of Fe on Ge(001) has been comprehensively studied by using a ultra-high vacuum in-situ transmission electron microscope. The reactive deposition of Fe on Ge(001) lead to the formation of hexagonal Fe13Ge8 islands on the cubic Ge surface at all temperatures studied. It has b...
