Ultrafast dynamics of excitons in black phosphorus
Geoffroy Kremer, Juan F. P. Mosquera, Joël Morf +9
Excitons are key quasiparticles determining the optical properties of solids. As such, they can be utilized to coherently control the electronic structure of materials using optica…

Mexican hat-like valence band dispersion and quantum confinement in rhombohedral ferroelectric alpha-In2Se3
Geoffroy Kremer, Aymen Mahmoudi, Meryem Bouaziz +9
Two-dimensional (2D) ferroelectric (FE) materials offer a large variety of electronic properties depending on chemical composition, number of layers and stacking-order. Among them,…

Revealing electronic correlations in YNiBC using photoemission spectroscopy
Aki Pulkkinen, Geoffroy Kremer, Vladimir N. Strocov +3
We present a combined density functional theory (DFT), one-step model of photoemission, and soft x-ray angle-resolved photoemission spectroscopy (SX-ARPES) study of the electronic…
