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…
Highly Efficient Exciton Modulation in MoSe/PdSe Heterostructures
Petr Rozhin, Emma Contin, Danae Katrisioti +15
Controlling exciton recombination in atomically thin semiconductors is central to their optoelectronic functionality, as the competition between radiative and non-radiative decay c…
Valleytronics in 2D Materials Roadmap
Kyle L. Seyler, Giancarlo Soavi, Bent Weber +30
Valleytronics exploits non-equivalent energy extrema in the electronic band structure of crystalline solids -- the valley degree of freedom -- to encode, manipulate, and read out i…
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…
