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…
Electron density control in tungsten diselenide monolayers via photochlorination
E. Katsipoulaki, G. Vailakis, I. Demeridou +8
Modulation of the Fermi level using an ultraviolet (UV)-assisted photochemical method is demonstrated in tungsten diselenide monolayers. Systematic shifts and relative intensities…
