Harnessing Exciton-Exciton Annihilation in Two-Dimensional Semiconductors
Eric Linardy, Dinesh Yadav, Daniele Vella +6
Strong many-body interactions in two-dimensional (2D) semiconductors give rise to efficient exciton-exciton annihilation (EEA). This process is expected to result in the generation…
Monolayer black phosphorus by sequential wet-chemical surface oxidation
Stefan Wild, Vicent Lloret, Victor Vega-Mayoral +11
We report a straightforward chemical methodology for controlling the thickness of black phosphorus flakes down to the monolayer limit by layer-by-layer oxidation and thinning, usin…
Suppressed out-of-plane polarizability of free excitons in monolayer WSe
Ivan A. Verzhbitskiy, Daniele Vella, Kenji Watanabe +2
Monolayer semiconductors are atomically thin quantum wells with strong confinement of electrons in two-dimensional (2D) plane. Here, we experimentally study the out-of-plane polari…
Elastomeric waveguide on-chip coupling of an encapsulated MoS monolayer
Filip Auksztol, Daniele Vella, Ivan Verzhbitskiy +6
We propose a robust photonic platform for encapsulation and addressing of optically active 2D- and nano-materials. Our implementation utilises a monolayer of MoS transition met…
Electroabsorption in MoS
Daniele Vella, Dmitry Ovchinnikov, Nicola Martino +8
To translate electrical into optical signals one uses the modulation of either the refractive index or the absorbance of a material by an electric field. Contemporary electroabsorp…
