چکیده
Received Mar 10, 2017 Revised May 5, 2017 Accepted May 26, 2017 Graphene is a promising new material for the construction of graphene devices because of its surface modification can be tuned the band gap. In this paper, the electronic and transport characteristics of defected graphene device are investigated. Both the electronic and transport characteristics are simulated using density functional theory (DFT). The band structures and transmission spectra are analyzed. The conductance and thermal conductance characteristic for both graphene is compared. From the simulation, it is found that the conductance, thermal conductance, and the I-V curves depend on the transmission spectrum of the graphene sheet or graphene device itself. The comparison between the defected graphene itself shows that the single layer with two vacancies shows better performance. Keyword:

متن کاملQuantum 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...

Graphene sheet including single vacancy, double vacancy and Stone-Wales with armchair and zigzag structure was simulated using molecular dynamics simulation. The effect of defects on shear’s modulus, shear strength and fracture strain was investigated. Results showed that these shear properties reduce when the degrees of all kinds of defects increase. The dangling bond in SV and DV defected gr...
متن کاملAccurate Six-Band Nearest-Neighbor Tight-Binding Model for the Ï•-Bands of Bulk Graphene and Graphene Nanoribbons
Accurate modeling of the S-bands of armchair graphene nanoribbons (AGNRs) requires correctly reproducing asymmetries in the bulk graphene bands as well as providing a realistic model for hydrogen passivation of the edge atoms. The commonly used single-p z orbital approach fails on both these counts. To overcome these failures we introduce a nearest-neighbor, three orbital per atom p/d tight-bin...
متن کاملGraphene on the C-terminated SiC (000 1) surface: An ab initio study
The atomic and electronic structures of a graphene layer on top of the (2 × 2) reconstruction of the SiC (0001̄) surface are studied from ab initio calculations. At variance with the (0001) face, no C bufferlayer is found here. Si adatoms passivate the substrate surface so that the very first C layer presents a linear dispersion characteristic of graphene. A small graphene-substrate interaction ...
