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…
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…
Hybridization in van der Waals epitaxy of PtSe2/h-BN and PtSe2/graphene heterostructures
Meryem Bouaziz, Samir El Masaoudi, Aymen Mahmoudi +10
Van der Waals (vdW) heterostructures, which combine bi-dimensional materials of different properties, enable a range of quantum phenomena. Here, we present a comparative study betw…
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,…
