The outstanding chemical and physical properties of 2D materials, together with their
atomically thin nature, make them ideal candidates for metaphotonic device integration and …

The electronic properties of graphene, a two-dimensional crystal of carbon atoms, are
exceptionally novel. For instance, the low-energy quasiparticles in graphene behave as …

We present an overview of the main techniques for production and processing of graphene
and related materials (GRMs), as well as the key characterization procedures. We adopt …

Mechanical deformation of a crystal can have a profound effect on its physical properties.
Notably, even small modifications of bond geometry can completely change the size and …

We present first-principles calculations of electronic properties of graphene under uniaxial
and isotropic strains, respectively. The semimetallic nature is shown to persist up to a very …

Two-phonon Raman scattering in graphitic materials provides a distinctive approach to
probing the material's electronic structure through the spectroscopy of phonons. Here we …

We study α, β, and γ graphyne, a class of graphene allotropes with carbon triple bonds,
using a first-principles density-functional method and tight-binding calculation. We find that …

Under homogeneous uniaxial strains, the Raman 2 D band of graphene involving two-
phonon double-resonance scattering processes splits into two peaks and they altogether …

The mechanical behavior of high quality two-dimensional (2D) crystals offers exciting
opportunities for new material design, such as the combination of extremely high in-plane …

We present a systematic experimental and theoretical study of the two-phonon (2D) Raman
scattering in graphene under uniaxial tension. The external perturbation unveils that the 2D …
