Transition metal oxides topological Dirac semimetals

Tuesday, 12.04.2016 14:00 - 15:00

Gang Li (TU Wien, Institute of Solid State Physics)

Abstract: Topological Dirac semimetals (DSMs) exhibit nodal points through which energy bands disperse linearly in three-dimensional (3D) momentum space, a 3D analogue of graphene. The first experimentally confirmed DSMs with a pair of Dirac points (DPs), Na3Bi and Cd3As2, show topological surface Fermi arc states and exotic magneto-transport properties, boosting the interest in the search for stable and nontoxic DSM materials.

Nanoluminescence, nanoscintillators

Tuesday, 19.04.2016 13:00 - 14:30

Prof. Christophe Dujardin (ILM, University C. Bernard, Lyon I. )

Scintillating materials convert into UV, Visible or IR photon ionizing radiations (γ, X, electrons...). They are used in many devices dedicated to radiation detection in medical imaging, homeland security, calorimetry for high energy physics and others.

In order to optimize the scintillating performances to various applications, many scintillating compositions have been developed so far. Beyond the composition, the material shape is also crucial and some times very specific for some detectors. Thin films, needles or fibers are currently used or under development.
