We have investigated the thermal conductivity of graphene nanoribbons (GNRs) with different edge shapes as a function of length, width, and strain using nonequilibrium molecular dynamics method. The initial GNR for the functional variations has dimensions of 2×11 nm2. Strong length dependence of thermal conductivity is obtained, indicating high thermal conductivities of GNRs, which is consistent with the experimental results for graphene. A tensile/compressive uniaxial strain can remarkably decrease the thermal conductivity of GNR.

    We evaluate the effect of stretching on the optical conductance of graphene. It is found that the low energy (Dirac regime) isotropy that leads to the “universal conductance” is lost. More significantly, due to the loss of C3 symmetry, a nonzero Hall conductance emerges for...

    The nature of the magnetic states of zigzag graphene nanoribbons (ZGNRs) was explored on the basis of density functional calculations to understand why they are apparently nonmagnetic. Our study shows that the magnetic moments of ZGNRs are destroyed by p-type or n-type carrier doping with...

In doing so, we determine that regardless of the chirality for monolayer...

One phenomenological expression is admitted, while all others are rejected because they cannot admit stable periodic ripple mode. The admitted...
