Interplay between magnetism and band topology in Dirac/Weyl semimetals KU Leuven
The quantum Hall effect (QHE), in which the transverse conductance of a two-dimensional (2D) electron gas in an applied magnetic field becomes quantized to multiples of e²/h, has fascinated physicists for over forty years. In 2013, the quantum anomalous Hall effect (QAHE) was realized in magnetic topological insulators. The hallmark of the QAHE is its dissipationless chiral 1D state running along the edge of the quasi-2D thin film, resulting ...
Electron correlations and non-trivial band topology in 2D materials KU Leuven
Phenomena originating from strong electron correlations and non-trivial band topology have become one of the main research areas in modern condensed matter physics and are expected to revolutionise future technology. Especially, quantum anomalous Hall effect (QAHE) has been observed in topological insulators, leading to dissipation-less spin-polarised current. So far, QAHE has been experimentally observed in a few systems. In this project, we ...
Local probing of low−dimensional dilute magnetic materials KU Leuven
The proposed research program is devoted to low−dimensional magnetic materials. Model systems consist of non-magnetic materials (with emphasis on 3-dimensional and 2-dimensional semiconductors and insulators) that are magnetically doped. The main goal is to provide a detailed understanding of the local structure, local magnetism and how they are coupled, using complementary local probe techniques based on intense particle beams (radioactive ...
Epitaxial oxides KU Leuven
All physical properties in solids come alive because of a specific interatomic arrangement, whether in crystalline or amorphous materials. For compounds such as metal oxides, additional parameters such as the metal valence state and the composition play a dominant role. While in principle one could imagine an infinite amount of atomic arrangements to be possible, it turns out that when a significant amount of atoms agglomerate together to ...
