Electronic transmission in Graphene suppressed by interlayer interference
Daniel Valencia, Jun-Qiang Lu, Jian Wu +3
We investigate electronic transport property of a graphene monolayer covered by a graphene nanoribbon. We demonstrate that electronic transmission of a monolayer can be reduced whe…
Nanoscale capacitance: a classical charge-dipole approximation
Jun-Qiang Lu, Jonathan Gonzalez, Carlos Sierra +1
Modeling nanoscale capacitance presents particular challenge because of dynamic contribution from electrodes, which can usually be neglected in modeling macroscopic capacitance and…
Annular wave packets at Dirac points and probability oscillation in graphene
Ji Luo, Junqiang Lu, Daniel Valencia
Wave packets in graphene whose central wave vector is at Dirac points are investigated by numerical calculations. Starting from an initial Gaussian function, these wave packets for…
Structural Trends Interpretation of the Metal-to-Semiconductor Transition in Deformed Carbon Nanotubes
Jun-Qiang Lu, Jian Wu, Wenhui Duan +2
Two mechanisms that drive metal-to-semiconductor transitions in single-walled carbon nanotubes are theoretically analyzed through a simple tight-binding model. By considering simpl…
Effects of Finite Deformed Length in Carbon Nanotubes
Jun-Qiang Lu, Jian Wu, Wenhui Duan +1
The effect of finite deformed length is demonstrated by squashing an armchair (10,10) single-walled carbon nanotube with two finite tips. Only when the deformed length is long enou…
Metal-to-semiconductor transition in squashed armchair carbon nanotubes
Jun-Qiang Lu, Jian Wu, Wenhui Duan +3
We investigate electronic transport properties of the squashed armchair carbon nanotubes, using tight-binding molecular dynamics and Green's function method. We demonstrate a metal…
