Ru2Si3 suicide was prepared in two different ways: (i) through a deposition (D) from a Ru2Si3 sputtering target and (ii) via a solid state reaction (SSR) of ruthenium thin filrri with silicon to form a rectifying structure silicide/silicon. Both types of silicides were treated at 700 degrees C in nitrogen ambient for 5 mm in order to facilitate crystallization and solid state reaction, respectively. Transmission electron microcopy (TEM), x-ray photoelectron spectroscopy (XPS) and Raman spectroscopy were applied to study structural, compositional and chemical properties of the two types of suicides.
