The transport properties of graphene T-type structure (GTS), both armchair-edged and zigzag-edged, are studied systematically within Landauer formalism in terms of tight binding Green's function method. For armchair-edged GTS (AGTS), a phase diagram of conductance in parameter space of Fermi ...
We present a detailed study of the high-current transport properties of graphene devices patterned in a four-point configuration. The current tends to saturate as the voltage across graphene is increased but never reaches the complete saturation as in metallic nanotubes. Measurements are compared to ...
The calculations also found that if the stacks were sufficiently pure (comparable to the cleanest graphene monolayers reported in the literature), a transport measurement could be used to identify the number of layers, the stacking orientation, and whether the dominant disorder was due to short-rang...
Directional Control of the Electronic and Transport Properties of Graphynes The Dirac energy dispersion, presented by graphene and other 2D materials, provides exquisite properties that are very useful for the design of new devices. A new class of 2D materials consisting only of carbon atoms and tha...
Understanding the influence of grain boundaries (GBs) on the electrical and thermal transport properties of graphene films is essentially important for electronic, optoelectronic and thermoelectric applications. Here we report a segregation–adsorption c
states in graphene depend on the edge termination ?zigzag or armchair? and affect the physical properties of nanoribbons. Different types of disorder modify the Dirac equation leading to unusual spectroscopic and transport properties. The effects of electron-electron and electron-phonon interactions in ...
Edge (surface) states in graphene are strongly dependent on the edge termination (zigzag or armchair) and affect the physical properties of nanoribbons. We also discuss how different types of disorder modify the Dirac equation leading to unusual spectroscopic and transport properties. The effects of ...
In studying large scale graphene structures it is necessary to consider the grain boundaries between the many single-crystal domains. The disruption of the crystallographic structure has consequences for both the electronic and transport properties. Although there has been much interest in this area in...
As an emerging type of nanomaterials, graphene and its derivatives are widely used in industry and daily products. Once released into environment, these nanomaterials would interact with colloids and then impact the transport behaviors of colloids in natural environment. This study found that the copr...
In this paper, by considering two numerical experiments simulating charge and phonon transport in graphene, two different definitions of local lattice temperature are investigated: one based on the properties of the phonon–phonon collision operator, and the other based on energy Lagrange multipliers. ...
