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…
Meeting the Scaling Challenge for Post-Silicon Nanoelectronics using CaF2 Insulators
Yury Yu. Illarionov, Alexander G. Banshchikov, Dmitry K. Polyushkin +10
Two-dimensional (2D) semiconductors have been suggested both for ultimately-scaled field-effect transistors (FETs) and More-than-Moore nanoelectronics. However, these targets can n…
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…
Imaging the dynamics of free-electron Landau states
P. Schattschneider, Th. Schachinger, M. Stöger-Pollach +4
Landau levels and states of electrons in a magnetic field are fundamental quantum entities underlying the quantum-Hall and related effects in condensed matter physics. However, the…
Atomic scale electron vortices for nanoresearch
J. Verbeeck, P. Schattschneider, S. Lazar +4
Electron vortex beams were only recently discovered and their potential as a probe for magnetism in materials was shown. Here we demonstrate a new method to produce electron vortex…
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…
