Temperature-Dependent Dielectric Function of Calcium Fluoride
T. Das, D. Alam, C. A. Ullrich +1
The optical properties of calcium fluoride (fluorspar, CaF2) are mainly determined by a strongly temperature-dependent giant infrared (IR) peak, and a series of nearly temperature-…

Coupled Oscillators and Dielectric Function
T. Das, C. A. Ullrich, U. D. Jentschura
A generalized Sellmeier model, also referred to as the Lorentz-Dirac model, has been used for the description of the dielectric function of a number of technologically important ma…
