Nonlinear dark-field imaging of 1D defects in monolayer dichalcogenides

Bruno R. Carvalho, Yuanxi Wang, Kazunori Fujisawa +10

Extended defects with one dimensionality smaller than that of the host, such as 2D grain boundaries in 3D materials or 1D grain boundaries in 2D materials, can be particularly dama…

Achieving Large, Tunable Strain in Monolayer Transition-Metal Dichalcogenides

Abdollah, M. Dadgar, Declan Scullion +7

We describe a facile technique based on polymer encapsulation to apply several percent controllable strains to monolayer and few-layer Transition Metal Dichalcogenides (TMDs). We u…

Characterizing top gated bilayer graphene interaction with its environment by Raman spectroscopy

D. L. Mafra, P. Gava, L. M. Malard +6

In this work we study the behavior of the optical phonon modes in bilayer graphene devices by applying top gate voltage, using Raman scattering. We observe the splitting of the Ram…

On the inner Double-Resonance Raman scattering process in bilayer graphene

D. L. Mafra, E. A. Moujaes, R. W. Nunes +1

The dispersion of phonons and the electronic structure of graphene systems can be obtained experimentally from the double-resonance (DR) Raman features by varying the excitation la…

Observation of the Kohn anomaly near the K point of bilayer graphene

D. L. Mafra, L. M. Malard, S. K. Doorn +4

The dispersion of electrons and phonons near the K point of bilayer graphene was investigated in a resonant Raman study using different laser excitation energies in the near infrar…
