Temperature-dependent generalized ellipsometry of the metal-insulator phase transition in low-symmetry charge-transfer salts
Achyut Tiwari, Bruno Gompf, Martin Dressel
Determining the optical and electronic properties of strongly anisotropic materials with symmetries below orthorhombic remains challenging; generalized ellipsometry is a powerful t…
Equivalence of light transport and depolarization
Maximilian Gill, Bruno Gompf, Martin Dressel +1
The study of scattered polarized light has led to important advances in distinct fields such as astronomy, atmospheric sciences and bio-imaging. In random diffusing media, light di…
Interaction of edge exciton polaritons with engineered defects in the van der Waals material Bi2Se3
Robin Lingstaedt, Nahid Talebi, Mario Hentschel +5
Hyperbolic materials exhibit unique properties that enable a variety of intriguing applications in nanophotonics. The topological insulator Bi2Se3 represents a natural hyperbolic o…
Microscopic nature of the asymmetric hysteresis in the insulator-metal transition of VO revealed by spectroscopic ellipsometry
Ievgen Voloshenko, Florian Kuhl, Bruno Gompf +4
Systematic spectroscopic ellipsometry investigations have been performed in order to elucidate the asymmetric insulator-to-metal transition in thin VO films. The comprehensive…
Dielectric properties of ultrathin metal films around the percolation threshold
Martin Hövel, Martin Alws, Bruno Gompf +1
We report on optical reflection measurements of thin Au films at and around the percolation threshold (film thickness 3 to 10 nm) in an extremely broad spectral range from 500 to 3…
Temperature and frequency dependent optical properties of ultra-thin Au films
Tobby Brandt, Martin Hövel, Bruno Gompf +1
While the optical properties of thin metal films are well understood in the visible and near-infrared range, little has been done in the mid- and far-infrared region. Here we inves…
