In this paper, we analyzed the influence of changing the material of electrodes on the transport properties of single junction comprising GNR (Graphene Nano Ribbon) stringed to two semi-infinite electrodes using semi empirical model. The investigation of electron transport through GNR was accomplished by linking it to different metallic electrodes (Pt, Au and Ag) under different bias voltages w...

The effects of edge chemistry on the relative stability and electronic properties of zigzag boron nitride nanoribbons (ZBNNRs) are investigated. Among all functional groups considered, fully hydroxylated ZBNNRs are found to be the most energetically stable. When an in-plane external electric field is applied perpendicular to the axis of both hydrogenated and hydroxylated ZBNNRs, a spin-polarize...

We describe the design and synthesis of a new graphene ribbon architecture that consists of perylenediimide (PDI) subunits fused together by ethylene bridges. We created a prototype series of oligomers consisting of the dimer, trimer, and tetramer. The steric congestion at the fusion point between the PDI units creates helical junctions, and longer oligomers form helical ribbons. Thin films of ...

We proposed a scheme of armchair graphene nanoribbon (AGNR) based tunnel field-effect transistor (TFET). The simulated device consists two electrodes with zigzag termination that are separated by narrow gap. Fermi level is controlled common back gate. main idea on taking advantage the electronic effects smooth edge atoms and investigatinge effect applied small uniaxial tensile strain gate volta...

in this research, graphene was synthesized by chemical vapor deposition (cvd) method in atmosphere pressure (14.7 psi). different functionalization method was used for oxidizing of graphene such as acid and alkaline treatments. the functionalized graphene (fg) was characterized by ftir and raman spectroscopy. nanofluid with water and different concentration (0.05, 0.15 and 0.25 wt %) of fg were...

in this study, an efficient and facile technique for preparing graphene oxide in suspension and powder forms was presented based on a modification on hummers' method followed by an additional ultrasonic process. the method involved the provision of graphene oxide from graphite by reaction of potassium permanganate and sulfuric acid with stabilizing the medium complex. furthermore, this stu...
