Abstract

Near-normal incidence reflectance of two different samples of mechanically polished, 99.97% pure, polycrystalline molybdenum was measured at 6121 spectral positions through the 0.0223–6.2-eV (180–50,000-cm⁻¹) spectral range. A composite reflectance spectrum of Mo was obtained by objectively combining the reflectance spectra of the two samples. A Drude free-electron model was fitted to the composite reflectance spectrum in the 0.0223–0.062-eV region; the composite reflectance spectrum was thus extended into the 0–0.0223-eV region. In the 5.56–2000-eV region reflectance values obtained from the literature¹ joined very well with the composite reflectance spectrum. Kramers-Kronig analysis of the reflectance spectrum provided the complex dielectric function, refractive index, and optical conductivity. We briefly review spectral values of these optical properties of Mo previously determined by other investigators, and we graphically compare results from our investigations with those from the previous investigations.
