Nature of the positron state in CdSe quantum dots
Wenqin Shi, Vincent Callewaert, Bernardo Barbiellini +11
Previous studies have shown that positron-annihilation spectroscopy is a highly sensitive probe of the electronic structure and surface composition of ligand-capped semiconductor Q…
The Anomalous Hall Effect in Magnetic Topological Insulators
Amir Sabzalipour, Bart Partoens
The anomalous Hall effect (AHE) is studied on the surface of a 3D magnetic topological insulator. By applying a modified semi-classical framework, all three contributions to the AH…
First-principles study of CO and OH adsorption on In-doped ZnO surfaces
R. Saniz, N. Sarmadian, B. Partoens +6
We present a first-principles computational study of non-polar ZnO (100) surfaces doped with indium. The calculations were performed using a model ZnO slab. The position o…
Tuning the electronic properties of gated multilayer phosphorene: A self-consistent tight-binding study
L. L. Li, B. Partoens, F. M. Peeters
By taking account of the electric-field-induced charge screening, a self-consistent calculation within the framework of the tight-binding approach is employed to obtain the electro…
Crystalline topological states at a topological insulator junction
Christophe De Beule, Rolando Saniz, Bart Partoens
We consider an interface between two strong time-reversal invariant topological insulators having surface states with opposite spin chirality, or equivalently, opposite mirror Cher…
Advanced first-principles theory of superconductivity including both lattice vibrations and spin fluctuations: The case of FeB
Jonas Bekaert, Alex Aperis, Bart Partoens +2
We present an advanced method to study spin fluctuations in superconductors quantitatively, and entirely from first principles. This method can be generally applied to materials wh…
