Spin polarization and attosecond time delay in photoemission from solids

Mauro Fanciulli

In the photoemission process electrons are emitted from a solid upon excitation with UV light. From the measurement of their energy and momentum, angle-resolved photoemission spectroscopy (ARPES) allows to reconstruct the electronic properties of the solid ...

Time-resolved ARPES at LACUS: Band Structure and Ultrafast Electron Dynamics of Solids

Majed Chergui, Marco Grioni, Arnaud Magrez, Helmuth Berger, Frank van Mourik, Philippe Bugnon, Alberto Crepaldi, Christopher Alexander Arrell, Gianmarco Gatti, José Javier Pancracio Ojeda Andara, Silvan Dino Marcos Roth

The manipulation of the electronic properties of solids by light is an exciting goal, which requires knowledge of the electronic structure with energy, momentum and temporal resolution. Time- and angle-resolved photoemission spectroscopy (tr-ARPES) is the ...

Experimental determination of Rashba and Dresselhaus parameters and g*- factor anisotropy via Shubnikov-de Haas oscillations

Dirk Grundler, Florian Herzog

The spin splitting of conduction band electrons in inversion-asymmetric InGaAs/InP quantum wells (QWs) is studied by Shubnikov-de Haas measurements combining the analysis of beating patterns and coincidence measurements in doubly tilted magnetic fields. Th ...

Surface-to-volume ratio controls the radiation of stratified plasmonic antennas

Olivier Martin, Christian Santschi, Banafsheh Abasahl

Surface plasmons are excited at a metal/dielectric interface, through the coupling between conduction electrons and incident photons. The surface plasmon generation is therefore strongly determined by the accessibility of the surface to the incoming electr ...

Manipulation of the Two-Dimensional States at Titanates Surfaces studied by ARPES

Stefan Peter Muff

The transition metal oxides are known for their versatile physical properties and are therefore an active field of research towards possible new functionalities and applications. This thesis focuses on the subgroup of titanates with perovskite structure th ...

Strain-induced polar discontinuities in two-dimensional materials from combined first-principles and Schrodinger-Poisson simulations

Giovanni Pizzi, Marco Gibertini, Augustin Bussy

The local application of mechanical stress in piezoelectric materials gives rise to boundaries across which the electric polarization changes. Polarization charges appear along such polar discontinuities and the ensuing electric fields drive a charge recon ...

eQE: An open-source density functional embedding theory code for the condensed phase

Oliviero Andreussi

In this work, we present the main features and algorithmic details of a novel implementation of the frozen density embedding (FDE) formulation of subsystem density functional theory (DFT) that is specifically designed to enable ab initio molecular dynamics ...
