Composition and Structure of a Nanofilm Multilayer System of the SiO2/Si/CoSi2/Si(111) Type Obtained via Ion Implantation
A SiO2/Si/CoSi2/Si(111) heterostructure is synthesized via successive Co+- and O 2 + -ion implantation into silicon followed by annealing. The optimal implantation and annealing conditions needed to obtain such a structure are determined. It is demonstrated that CoSi2 and SiО2 layers formed in the surface region are single- and polycrystalline, respectively.
