Room temperature valley coherence in monolayer WSe2 mediated by chiral nematic liquid crystal
Hassan Lamsaadi, Andrea Balocchi, Aurélien Cuche +5
Valley coherence refers to a phase-coherent superposition of inequivalent momentum valleys, in which quantum information can be encoded in the relative valley phase. Chiral nematic…
Emergence of Localized Surface Plasmons in Unpatterned Hyperdoped Polycrystalline Silicon
Mohamad Bahsoun, Jesse Groenen, Gonzague Agez +7
The ability to engineer localized surface plasmon resonances at large scale usually relies on precise nanoscale patterning. Here, we demonstrate that mid-infrared plasmonic respons…
2D Excitonics with Atomically Thin Lateral Heterostructures
S. Shradha, R. Rosati, H. Lamsaadi +18
Semiconducting transition metal dichalcogenides (TMDs), such as MoSe and WSe, exhibit unique optical and electronic properties. Vertical stacking of layers of one or more T…
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…
