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,…
Persistence of structural distortion and bulk band Rashba splitting in SnTe above its ferroelectric critical temperature
Frédéric Chassot, Aki Pulkkinen, Geoffroy Kremer +8
The ferroelectric semiconductor -SnTe has been regarded as a topological crystalline insulator and the dispersion of its surface states has been intensively measured with angle-…
Intrinsic defects and mid-gap states in quasi-one-dimensional Indium Telluride
Meryem Bouaziz, Aymen Mahmoudi, Geoffroy Kremer +9
Recently, intriguing physical properties have been unraveled in anisotropic semiconductors, in which the in-plane electronic band structure anisotropy often originates from the low…
Quantum Confinement and Electronic Structure at the Surface of van der Waals Ferroelectric α-InSe
Geoffroy Kremer, Aymen Mahmoudi, Adel M'Foukh +11
Two-dimensional (2D) ferroelectric (FE) materials are promising compounds for next-generation nonvolatile memories, due to their low energy consumption and high endurance. Among th…
Carrier-Density Control of the Quantum-Confined 1-TiSe Charge-Density-Wave
T. Jaouen, A. Pulkkinen, M. Rumo +9
Using angle-resolved photoemission spectroscopy, combined with first principle and coupled self-consistent Poisson-Schrödinger calculations, we demonstrate that potassium (K) atoms…
