Quadrupolar and Dipolar Excitons in Bilayer 2-MoSe
Shun Feng, Aidan J. Campbell, Bibi Mary Francis +6
We report the experimental observation of quadrupolar exciton states in the reflectance contrast spectrum of 2-stacked bilayer MoSe. The application of a vertical electric f…
Quasi van der Waals Epitaxy of Rhombohedral-stacked Bilayer WSe2 on GaP(111) Heterostructure
Aymen Mahmoudi, Meryem Bouaziz, Niels Chapuis +11
The growth of bilayers of two-dimensional (2D) materials on conventional 3D semiconductors results in 2D/3D hybrid heterostructures, which can provide additional advantages over mo…
Highly Tunable Ground and Excited State Excitonic Dipoles in Multilayer 2H-MoSe
Shun Feng, Aidan Campbell, Mauro Brotons-Gisbert +7
The fundamental properties of an exciton are determined by the spin, valley, energy, and spatial wavefunctions of the Coulomb bound electron and hole. In van der Waals materials, t…
Second harmonic generation control in twisted bilayers of transition metal dichalcogenides
Ioannis Paradisanos, Andres Manuel Saiz Raven, Thierry Amand +7
The twist angle in transition metal dichalcogenide (TMD) heterobilayers is a compelling degree of freedom that determines electron correlations and the period of lateral confinemen…
Capacitively-coupled and inductively-coupled excitons in bilayer MoS
Lukas Sponfeldner, Nadine Leisgang, Shivangi Shree +10
The interaction of intralayer and interlayer excitons is studied in a two-dimensional semiconductor, homobilayer MoS. It is shown that the measured optical susceptibility revea…
Multiwavelength electron diffraction as a tool for identifying stacking sequences in 2D materials
Pascal Puech, Iann Gerber, Fabrice Piazza +1
Two-dimensional (2D) materials are among the most studied ones nowadays, because of their unique properties. These materials are made of, single- or few atom-thick layers assembled…
