Size effect on the thermal conductivity of a type-I clathrate
Monika Lužnik, Günther Lientschnig, Mathieu Taupin +3
Clathrates are a materials class with an extremely low phonon thermal conductivity, which is a key ingredient for a high thermoelectric conversion efficiency. Here, we present a st…
Switching on surface conduction in a topological insulator
M. Taupin, G. Eguchi, M. Luznik +6
The protected surface conduction of topological insulators is in high demand for the next generation of electronic devices. What is needed to move forward are robust settings where…
Nanostructured clathrates and clathrate-based nanocomposites
R. Christian, M. Ikeda, G. Lientschnig +13
Intermetallic clathrates are candidate materials for thermoelectric applications above room temperature. Here we explore whether their intrinsically low lattice thermal conductivit…
EMCD with an electron vortex filter: Limitations and possibilities
Thomas Schachinger, Stefan Löffler, Andreas Steiger-Thirsfeld +5
We discuss the feasibility of detecting spin polarized electronic transitions with a vortex filter. This approach does not rely on the principal condition of the standard energy lo…
Sub-nanometer free electrons with topological charge
P. Schattschneider, M. Stöger-Pollach, S. Löffler +3
The holographic mask technique is used to create freely moving electrons with quantized angular momentum. With electron optical elements they can be focused to vortices with diamet…
