Enhanced thermoelectric figure of merit in edge-disordered zigzag graphene nanoribbons
We investigate electron and phonon transport through edge-disordered zigzag graphene nanoribbons based on the same methodological tool of nonequilibrium Green functions. We show that edge disorder…

Charge transport in disordered graphene-based low dimensional materials
Two-dimensional graphene, carbon nanotubes, and graphene nanoribbons represent a novel class of low dimensional materials that could serve as building blocks for future carbon-based nanoelectronics.…

Direct low-temperature nanographene CVD synthesis over a dielectric insulator.
TLDR
A facile chemical vapor deposition approach is reported in which nanographene and few-layernanographene are directly formed over magnesium oxide and can be achieved at temperatures as low as 325 degrees C.

Control of thermal and electronic transport in defect-engineered graphene nanoribbons.
TLDR
It is identified that defects close to the edges and relatively small values of edge roughness preserve the quasi-ballistic nature of electronic transport, which presents a route of independently controlling electrical and thermal transport by judicious engineering of the defect distribution.

Charge transport in DNA-based devices
TLDR
It is concluded that electrical transport is feasible in short DNA molecules, in bundles and networks, but blocked in long single molecules that are attached to surfaces.

Electronic structure of single DNA molecules resolved by transverse scanning tunnelling spectroscopy.
TLDR
The energy spectrum of poly(G)-poly(C) DNA molecules deposited on gold is disclosed by using scanning tunnelling spectroscopy at cryogenic temperature and limited fluctuations in the I-V curves are observed and statistically characterized.

Understanding the catalyst-free transformation of amorphous carbon into graphene by current-induced annealing
TLDR
In the presence of a–C, graphene can grow from the borders of holes and form a seamless graphene sheet, a novel finding that has not been reported before and that is reproduced by the simulations as well.

Contact dependence of carrier injection in carbon nanotubes: an ab initio study.
TLDR
It is suggested that the optimum metal-nanotube contact combines a weak hybridization with a large contact length between the metal and the nanotube.
