Graphene-based materials exhibit remarkable electronic, optical, and mechanical
properties, which has resulted in both high scientific interest and huge potential for a variety …

Magnetism in two-dimensional materials is not only of fundamental scientific interest but also
a promising candidate for numerous applications. However, studies so far, especially the …

How a certain ground state of complex physical systems emerges, especially in two-
dimensional materials, is a fundamental question in condensed-matter physics. A …

Raman spectroscopy is an integral part of graphene research. It is used to determine the
number and orientation of layers, the quality and types of edge, and the effects of …

Recent Raman scattering studies in different types of graphene samples are reviewed here.
We first discuss the first-order and the double resonance Raman scattering mechanisms in …

We calculate the double-resonant (DR) Raman spectrum of graphene, and determine the
lines associated to both phonon-defect processes (such as in the D line at∼ 1350 cm− 1 …

We report that highly crystalline graphene can be obtained from well-controlled surface
morphology of the copper substrate. Flat copper surface was prepared by using a chemical …

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 …

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 …
