我们发展了一种新的蒙特卡罗模拟模型来研究多层石墨烯纳米带(GNR)互连线的输运特性与边缘粗糙度之间的线宽关系。我们报道了随着边缘粗糙度的减小，载流子迁移率对线宽的依赖关系明显减小，这与实验结果吻合得很好。我们还讨论了边缘粗糙度散射的非弹性、层间隧道效应和依赖于线宽的能带结构对GNR互连线宽的影响。
We developed a novel Monte Carlo simulation model to investigate the line width dependence of the transport properties of multi-layered graphene nanoribbon (GNR) interconnects with edge roughness. We reported that the line width dependence of carrier mobility decreases significantly as the magnitude of the edge roughness gets smaller, which agrees well with experiments. We also discussed the influence of the inelasticity of edge roughness scatterings, inter-layer tunneling, and line width dependent band structures on the line width of the GNR interconnects.
