Highly tunable band structure in ferroelectric R-stacked bilayer WSe

Zhe Li, Prokhor Thor, George Kourmoulakis +6

Transition metal dichalcogenide homobilayers unite two frontiers of quantum materials research: sliding ferroelectricity, arising from rhombohedral (R) stacking, and moiré quantum…

Strain distribution in WS2 monolayers detected through Polarization-resolved Second Harmonic Generation

George Kourmoulakis, Sotiris Psilodimitrakopoulos, George Miltos Maragkakis +9

Two-dimensional (2D) graphene and graphene-related materials (GRMs) show great promise for future electronic devices. Nevertheless, GRMs result distinct properties under the influe…

Biaxial strain tuning of exciton energy and polarization in monolayer WS2

G. Kourmoulakis, A. Michail, I. Paradisanos +8

We perform micro-photoluminescence and Raman experiments to examine the impact of biaxial tensile strain on the optical properties of WS2 monolayers. A strong shift on the order of…

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…

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…
