Alloy engineering of excitonic properties in TMD monolayers
Eirini Katsipoulaki, Adlen Smiri, Panagiotis Spiliotakis +12
We investigate monolayer MoSSe alloys across the full composition range using optical spectroscopy. We demonstrate continuous tuning of the optical gap over $\sim…
Silicon nanoantennas for tailoring the optical properties of MoS2 monolayers
Danae Katrisioti, Peter R. Wiecha, Aurélien Cuche +11
Silicon-based dielectric nanoantennas provide an effective platform for engineering light-matter interactions in van der Waals semiconductors. Here, we demonstrate near-field coupl…
Spin-valley polarization control in WSe monolayers using photochemical doping
E. Katsipoulaki, K. Mourzidis, V. Jindal +9
We report on the influence of a photochemical doping method on the spin-valley polarization degree () of excitons in WSe monolayers. By varying the carrier density and t…
Anisotropic Third Harmonic Generation in Two-Dimensional Tin Sulfide
George Miltos Maragkakis, Sotiris Psilodimitrakopoulos, Leonidas Mouchliadis +4
The in-plane anisotropic properties of two-dimensional (2D) group IV monochalcogenides provide an additional degree of freedom which can be used in future optoelectronic devices. H…
Strain distribution in WS2 monolayers detected through Polarization-resolved Second Harmonic Generation
George Kourmoulakis, Sotiris Psilodimitrakopoulos, George Miltos Maragkakis +9
Two-dimensional (2D) graphene and graphene-related materials (GRMs) show great promise for future electronic devices. Nevertheless, GRMs result distinct properties under the influe…
Biaxial strain tuning of exciton energy and polarization in monolayer WS2
G. Kourmoulakis, A. Michail, I. Paradisanos +8
We perform micro-photoluminescence and Raman experiments to examine the impact of biaxial tensile strain on the optical properties of WS2 monolayers. A strong shift on the order of…
