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…

Dipolar interlayer excitons in transition metal dichalcogenide alloy heterobilayers
E. Katsipoulaki, N. G. Chatzarakis, E. Rigoutsou +6
Interlayer excitons in transition metal dichalcogenide (TMD) heterobilayers possess a permanent electric dipole moment and long recombination lifetimes, making them a promising pla…

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…
