Prominent room temperature valley polarization in WS2/graphene heterostructures grown by chemical vapor deposition
Ioannis Paradisanos, Kathleen M. McCreary, Davoud Adinehloo +8
We examine different cases of heterostructures consisting of WS2 monolayers grown by chemical vapor deposition (CVD) as the optically active material. We show that the degree of va…
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…
Spatial Non-Uniformity in Exfoliated WS2 Single layers
I. Paradisanos, N. Pliatsikas, P. Patsalas +4
Monolayers of Transition Metal Dichalcogenides (TMDs) are atomically thin two-dimensional crystals with attractive optoelectronic properties, which are promising for emerging appli…
