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 ...
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 chemical vapour deposition method to grow well-stitched hi...
The Dirac electrons behave in unusual ways in tunneling, confinement, and the integer quantum Hall effect. The electronic properties of graphene stacks are discussed and vary with stacking order and number of layers. Edge surface states in graphene depend on the edge termination zigzag or armchair ...
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...

The transport behavior of graphene carriers has been intensively studied10,33,38,39,40,41,42,43,44,45,46,47,48,97 and can serve as a reliable system for testing new methods. Most importantly, this new method could also be used to improve the fundamental understanding of TMD and BP ...

Graphene oxide (GO) films are known to be highly stable in water and this property has made their use in membrane applications in solution possible. However, this state of affairs is somewhat counterintuitive because GO sheets become negatively charged o
Key to understanding the 2D MIT is the study of metallic transport near the transition. In 3D materials, it is known that weak-localization (WL) and enhanced electron-electron interactions (EEI) control the metallic transport properties near the MIT. For metallic graphene with moderately high ...
