Ultrafast transition from coherent to incoherent polariton nonlinearities in a hybrid 1L-WS2/plasmon structure
Daniel Timmer, Moritz Gittinger, Thomas Quenzel +14
Exciton polaritons based on atomically thin semiconductors are essential building blocks of quantum optoelectronic devices. Their properties are governed by an ultrafast and oscill…
Identification of exciton complexes in a charge-tuneable Janus WSeS monolayer
Matthew S. G. Feuer, Alejandro R. -P. Montblanch, Mohammed Sayyad +16
Janus transition-metal dichalcogenide monolayers are fully artificial materials, where one plane of chalcogen atoms is replaced by chalcogen atoms of a different type. Theory predi…
Revealing Interfaces of Two-Dimensional Lateral Heterostructures by Second Harmonic Generation
Frederico B. Sousa, Lucas Lafeta, Alisson R. Cadore +2
The interface between two different semiconductors is crucial in determining the electronic properties at the heterojunction, therefore novel techniques that can probe these region…
Tunable, grating-gated, graphene-on-polyimide terahertz modulators
Alessandra Di Gaspare, Eva A. A. Pogna, Luca Salemi +10
We present an electrically switchable graphene terahertz (THz) modulator with a tunable-by-design optical bandwidth and we exploit it to compensate the cavity dispersion of a quant…
Low-loss integrated nanophotonic circuits with layered semiconductor materials
Tianyi Liu, Ioannis Paradisanos, Jijun He +13
Monolayer transition metal dichalcogenides with direct bandgaps are emerging candidates for microelectronics, nano-photonics, and optoelectronics. Transferred onto photonic integra…
Efficient phonon cascades in hot photoluminescence of WSe monolayers
Ioannis Paradisanos, Gang Wang, Evgeny M. Alexeev +5
Energy relaxation of photo-excited charge carriers is of significant fundamental interest and crucial for the performance of monolayer (1L) transition metal dichaclogenides (TMDs)…
Confinement of long-lived interlayer excitons in WS/WSe heterostructures
Alejandro R. -P. Montblanch, Dhiren M. Kara, Ioannis Paradisanos +13
Interlayer excitons in layered materials constitute a novel platform to study many-body phenomena arising from long-range interactions between quantum particles. The ability to loc…
Niobium diselenide superconducting photodetectors
Gavin J. Orchin, Domenico De Fazio, Angelo Di Bernardo +10
We report the photoresponse of niobium diselenide (NbSe), a transition metal dichalcogenide (TMD) which exhibits superconducting properties down to a single layer. Devices are…
Charge-tuneable biexciton complexes in monolayer WSe
Matteo Barbone, Alejandro R. -P. Montblanch, Dhiren M. Kara +13
Multi-exciton states such as biexcitons, albeit theoretically predicted, have remained challenging to identify in atomically thin transition metal dichalcogenides so far. Here, we…
