Epitaxial Growth and Electronic Properties of QuasiFreeStanding Rhombohedral WSe2 Bilayers on Cubic W110
Niels Chapuis, Meryem Bouaziz, Eva Desgue +6
Rhombohedral-stacked transition metal dichalcogenides (TMDs) break inversion symmetry between adjacent layers, giving rise to an intrinsic out-of-plane ferroelectric polarization.C…
Tunable electronic band structure in WSSe van der Waals Alloys
Meryem Bouaziz, Leonard Schue, Noeliarinala Felana Andriambelaza +12
The electronic structure of semiconducting 2D materials such as transition metal dichalcogenides (TMDs) is known to be tunable by its environment, from simple external fields appli…
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,…
Distinguishing different stackings in WSe2 bilayers grown Using Chemical Vapor Deposition
Aymen Mahmoudi, Meryem Bouaziz, Davide Romani +6
The stacking order of two-dimensional transition metal dichalcogenides (TMDs) is attracting tremendous interest as an essential component of van der Waals heterostructures. A commo…
