Optical Properties of Indium

Abstract

Experimental measurements consisting of ellipsometry (Q.5-3.5 eV) and normal-incidence reflectance (3.0-11. 6 eV) are used along with published data to determine the optical constants of indium from 0.5 to 15.5 eV. Although the over-all properties reflect free-electron behavior, departures from Drude theory can be understood in terms of interband transitions.

Mie Resonances, Infrared Emission, and the Band Gap of InN

“…The complex dielectric function for indium is taken from Ref. [14]. Currently, there is uncertainty in the InN complex dielectric function.…”

Direct-drawn metamaterial fibers with magnetic response in the 100GHz range

“…The appropriate orientation of the resonators within our fibers with respect to the incident field was taken into account in our simulations. We included the refractive index for PMMA, PC [11] and indium [12] in this range, finding excellent agreement with experiment in both fiber orientations [ Fig. 2(a), bottom].…”

Optical properties of InN—the bandgap question

“…This expression can show strong resonances if the imaginary part of ε m is negative, which is true for In over a wide IR range [59]. This model has been compared with experimental data on optical absorption in InN layers containing In inclusions, obtained with the thermally detected optical absorption technique at very low temperatures (0.35 K) [46].…”
