Thermal Annealing of Graphene Implanted with Mn at Ultralow Energies: From Disordered and Contaminated to Nearly Pristine Graphene

Curling graphene ribbons through thermal annealing

A simple process is developed to curl graphene membranes through thermal annealing. The resulting curled graphene ribbons displayed enhanced photocurrent response compared to flat graphene ribbons. The annealing temperature, the thickness of the graphene, and the type of polymethyl methacrylate used were the three key factors that influenced the morphology of graphene during thermal annealing. ...

Synthesis and structural properties of Mn-doped ZnO/Graphene nanocomposite

Zinc oxide (ZnO) is a promising metal oxide semiconductor with various applications, especially in the photocatalytic destruction of environmental pollutants. However, this nanoparticle has some limitations, such as poor dispersion, aggregation, and a wide energy gap. As such, the doping of metal oxide semiconductor has been strongly recommended. Addition of manganese (Mn) has proven effective ...

Graphene and Graphene Multilayers: Phonon Thermal Transport

In this entry, we review thermal properties of graphene and multilayer graphene and discuss in detail the optothermal Raman technique developed for the thermal conductivity measurements. We also outline different theoretical approaches used for the description of phonon transport in graphene and provide comparison with the available experimental thermal conductivity data.

Graphene: a nearly perfect fluid.

Hydrodynamics and collision-dominated transport are crucial to understand the slow dynamics of many correlated quantum liquids. The ratio eta/s of the shear viscosity eta to the entropy density s is uniquely suited to determine how strongly the excitations in a quantum fluid interact. We determine eta/s in clean undoped graphene using a quantum kinetic theory. As a result of the quantum critica...
