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…
Strongly Enhanced Thermal Stability of Crystalline Organic Thin Films Induced by Aluminum Oxide Capping Layers
Stefan Sellner, Alexander Gerlach, Frank Schreiber +7
We show that the thermal stability of thin films of the organic semiconductor diindenoperylene (DIP) can be strongly enhanced by aluminum oxide capping layers. By thermal desorptio…
