چکیده مقاله:

In this paper, the magnetic properties of carbon based material, graphene is studied, which is generated by laser ablation in cryogenic media. Transmission electron microscopy (TEM) and alternating gradient force magnetometer (AGFM) are applied to investigate the graphene morphology and magnetic properties, respectively. The graphene synthesized by the laser ablation method exhibits diamagnetic behavior. However the magnetic transition from diamagnetic to paramagnetic effect is lucidly observed by functionalizing the graphene sample with silver atoms.

Synthesis of magnetic graphene-Fe3O4 nanocomposites by electrochemical exfoliation method

Superparamagnetic few-layer graphene nanocomposites (FLG- NCs) can be used for many technological applications, such as solar cells, batteries, touch panels and supercapacitors. In this work, we applied electrochemical exfoliation method as a simple, one step and economical technique to fabricate FLG- NCs. The fabricated Superparamagnetic FLG- NCs were characterized by X-ray diffraction (XRD), ...

Li diffusion through doped and defected graphene.

We investigate the effect of nitrogen and boron doping on Li diffusion through defected graphene using first principles based density functional theory. While a high energy barrier rules out the possibility of Li- diffusion through the pristine graphene, the barrier reduces with the incorporation of defects. Among the most common defects in pristine graphene, Li diffusion through the divacancy ...

Quantum transport modeling of defected graphene nanoribbons

We study backscattering phenomena during conduction for graphene nanoribbons of mm lengths, from single vacancy scatterers up to finite defect concentrations. Using ab initio calibrated Hamiltonian models we highlight the importance of confinement and geometry on the shaping of the local density of states around the defects that can lead to important alterations on the transport process, giving...

Laser Machining of Graphene

Since Geim and Novoselov’s successful production of high quality graphene, its unique properties have found a number of applications. But graphene is not an exotic chemical compound; instead, it is a sheet of graphite, one atom think. Before 2008, the only way to produce graphene was through successive pealing of graphite with scotch tape until graphite flakes as thin as 1 atomic layer were lef...
