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…
Detection of Image Potential States above the vacuum level in GeTe
Frédéric Chassot, Aki Pulkkinen, Ján Minár +3
The ferroelectric semiconductor α-GeTe(111) has attracted significant attention in the last decade due to its unique properties, with extensive studies focusing on its occupied el…
Suppression of stripe-ordered structural phases in monolayer IrTe by a gold substrate
Kati Asikainen, Frédéric Chassot, Baptiste Hildebrand +12
Metal-assisted exfoliation of two-dimensional (2D) materials has emerged as an efficient route to isolating large-area monolayer crystals, yet the influence of the supporting metal…
Conduction Band Structure and Ultrafast Dynamics of Ferroelectric -GeTe(111)
Geoffroy Kremer, Laurent Nicolaï, Frédéric Chassot +9
-GeTe(111) is a non-centrosymmetric ferroelectric (FE) material for which a significative lattice distortion combined with a strong spin-orbit interaction gives rise to giant R…
