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…
Twist Angle mapping in layered WS2 by Polarization-Resolved Second Harmonic Generation
Sotiris Psilodimitrakopoulos, Leonidas Mouchliadis, Ioannis Paradisanos +4
Stacked atomically thin transition metal dichalcogenides (TMDs) exhibit fundamentally new physical properties compared to those of the individual layers. The twist angle between th…
Room temperature observation of biexcitons in exfoliated WS2 monolayers
I. Paradisanos, S. Germanis, N. T. Pelekanos +4
Single layers of WS2 are direct gap semiconductors with high photoluminescence (PL) yield holding great promise for emerging applications in optoelectronics. The spatial confinemen…
