OPTICAL PROPERTIES OF CUBIC SILICON CARBIDE

Abstract Reflection Electron Energy Loss Spectroscopy (REELS) using a 1 keV electron beam has been used to obtain the reflectivity spectra and the complex dielectric constant of 3C-silicon carbide in the energy loss range 0–100 eV. The experimental results have been compared with the theoretical results obtained using the Linearized Muffin Tin Orbitals (LMTO–ASA) method. A reasonable agreement has been obtained between theory and experiment.
