Platinum Carbon Multilayer Grating: Preparation And Characterization

Platinum carbon (Pt/C) multilayer were deposited on silicon carbide (SiC) grating using an electron beam evaporation system. The bare SiC substrate and SiC grating were characterized by soft x-ray reflectivity measurements before coating with WC multilayer. Reflectivity and dispersion efficiencies of multilayer grating were measured using characteristic x-rays and synchrotron radiation.
