BaVS3 probed by V L edge x-ray absorption spectroscopy

Helmuth Berger, László Forró, Ana Akrap

Polarization dependent vanadium L edge x-ray absorption spectra of BaVS3 single crystals are measured in the four phases of the compound. The difference between signals with the polarizations E perpendicular to c and E parallel to c ( linear dichroism) cha ...

Graphene Sublattice Symmetry and Isospin Determined by Circular Dichroism in Angle-Resolved Photoemission Spectroscopy

Klaus Kern

The Dirac-like electronic structure of graphene originates from the equivalence of the two basis atoms in the honeycomb lattice. We show that the characteristic parameters of the initial state wave function (sublattice symmetry and isospin) can be determin ...

Refractive Index Gas Sensing in a Hollow Photonic Crystal Cavity

Romuald Houdré, Nicolas Le Thomas, Hua Zhang, Zhaolu Diao, Jana Jágerská

We investigate hollow photonic crystal structures consisting in air-slot photonic crystal nanocavities. The high quality factor similar to 2.6x10(4) of such cavities along with a strong overlap between the resonant mode and the hollow core region allows fo ...

Magnetic circular dichroism in electron energy loss spectrometry

Cécile Hébert

The measurement of circular dichroism in the electron microscope is a new, emerging method and, as such, it is subject to constant refinement and improvement. Different ways can be envisaged to record the signal. We present an overview of the key steps in ...

Linear dichroism of CdSe nanodots: Large anisotropy of the band-gap absorption induced by ground-state dipole moments

Majed Chergui, Frank van Mourik

The authors measured the elec. field induced linear dichroism for a wide range of sizes of CdSe nanocrystals. Large ground-state dipole moments were obsd., esp. for the smallest crystals. In these, the authors found a very large anisotropy of the absorptio ...

Effects of upstream hydropower operation and oligotrophication on the light regime of a turbid peri-alpine lake

Alfred Johny Wüest

Anthropogenic activities in catchments can alter the light regimes in downstream natural waters, affecting light attenuation and the perceived optical properties of the waters. We analyzed the effects of upstream hydropower operation and oligotrophication ...
