Abstract:Epitaxial Ru2Si3 has been successfully grown on (111) Si for the first time by using the new method of chemical electroless plating of Ru thin film on silicon with subsequent annealing schemes. The crystal structure of Ru2Si3 reported in the literature, which was identified by X-ray diffraction, was ambiguous to be tetragonal or orthorhombic. The study of stereomicroscopy and Kikuchi lines of the Ru2Si3 by scanning transmission electron microscopy shows that the structure of Ru2Si3 is orthorhombic with four-fold like symmetry rather than tetragonal.
