Abstract
The near-normal reflectivity of single-crystal from 0.01 to 8 eV and the dielectric functions obtained by Kramers-Kronig (KK) analysis are presented. The effect of an oxide overlayer on the optical properties is also considered. The low-energy response is discussed in terms of the Drude model; the higher-energy spectrum is interpreted on the basis of available information about the electronic structure. A comparison is made with the optical properties of pure Ti and other refractory-metal silicides.
