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…
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…
