Optical versus electron diffraction imaging of Twist-angle in 2D transition metal dichalcogenide bilayer superlattices
S. Psilodimitrakopoulos, A. Orekhov, L. Mouchliadis +7
Atomically thin two-dimensional (2D) materials can be vertically stacked with van der Waals bonds, which enable interlayer coupling. In the particular case of transition metal dich…
Wide field of view crystal orientation mapping of layered materials
A. Orekhov, D. Jannis, N. Gauquelin +10
Layered materials (LMs) are at the centre of an ever increasing research effort due to their potential use in a variety of applications. The presence of imperfections, such as bi-…
Probing valley population imbalance in transition metal dichalcogenides via temperature-dependent second harmonic generation imaging
Leonidas Mouchliadis, Sotiris Psilodimitrakopoulos, George Miltos Maragkakis +5
Degenerate minima in momentum space - valleys - provide an additional degree of freedom that can be used for information transport and storage. Notably, such minima naturally exist…
Modelling ultrafast non-equilibrium carrier dynamics and relaxation processes upon irradiation of hexagonal Silicon-Carbide with femtosecond laser pulses
G. D. Tsibidis, L. Mouchliadis, M. Pedio +1
We present a theoretical investigation of the yet unexplored dynamics of the produced excited carriers upon irradiation of hexagonal Silicon Carbide (6H-SiC) with femtosecond laser…
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…
