The temperature dependence of the complex dielectric function ϵ1+iϵ2 of bulk Ge near the direct bandgap was investigated with spectroscopic ellipsometry at temperatures between 10 and 710 K. Second derivatives of the dielectric function with respec

The dielectric function of Ge measured with static and time-resolved spectroscopic ellipsometry is analyzed using linear filtering techniques to investigate the temperature dependence of the direct band gap, as well as the temporal evolvement of crit

Ellipsometry measurements were taken on single-crystalline Ni(100) at various temperatures between 77 and 770 K. DC conductivity and resistivity are extracted from the model optical constants and their temperature dependence is discussed. The authors

The dielectric function of bulk Ge is determined between 0.5 and 6.3 eV in a temperature range of 10–738 K using spectroscopic ellipsometry. The authors provide the data in a tabulated format that can be interpolated as a function of photon energy

The temperature dependence of the dielectric function of Ge is investigated in a spectral range from 0.5 to 6.3 eV between 10 and 738 K. Structures occurring in the infrared region of α-Sn on InSb are compared to the absorption edge of Ge.

Using spectroscopic ellipsometry from 0.06 to 6.0 eV at room temperature, the authors determined the optical constants (complex dielectric function, refractive index, and optical conductivity) of bulk cold-rolled polycrystalline Ni. To reduce the thi

The factorized plasmon-phonon polariton description of the infrared dielectric function is generalized to include an additional factor to account for the effects of interband electronic transitions. This new formalism is superior to the usual Drude
