Temperature Dependence of Phonon Energies and Lifetimes in Single- and Few-layered Graphene
Markos Poulos, Konstantinos Papagelis, Emmenuel N. Koukaras +3
In this work, we have studied the phonon properties of multi-layered graphene with the use of Molecular Dynamics (MD) simulations and the k-space Autocorrelation Sequence (k-VACS)…
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 Tensile Strain Enhances Electron Mobility of Monolayer Transition Metal Dichalcogenides
Jerry A. Yang, Robert K. A. Bennett, Lauren Hoang +7
Strain engineering can modulate the material properties of two-dimensional (2D) semiconductors for electronic and optoelectronic applications. Recent theory and experiments have fo…
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…
Uniaxial Compression of Suspended Single and Multilayer graphenes
A. P. Sgouros, G. Kalosakas, C. Galiotis +1
The mechanical response of single and multiple graphene sheets under uniaxial compressive loads was studied with molecular dynamics simulations, using different semi-empirical forc…
Compression behavior of simply-supported and fully embedded monolayer graphene: theory and experiment
Emmanuel N. Koukaras, Charalampos Androulidakis, George Anagnostopoulos +2
Single layer graphene simply-supported on a polymer substrate was subjected to axial compression and its behavior upon loading was monitored with laser Raman spectroscopy (LRS). Th…
