Effect of interlayer coupling in charge transport across strongly disordered multilayer reduced graphene oxide

Charge transport across disordered multilayers, especially the precise role of interlayer interaction in promoting or jeopardizing electron flow, remains unclear. This work investigates charge transport across multilayer graphene oxide using a multiscale computational approach, which bridges first-principles calculations with large-scale transport simulations. It is observed that resistivity deviates from the well-known scaling laws. Also, the hierarchy of transport regimes between diffusion and localization is reversed. A scaling law for resistivity depending on the number of layers is proposed. The predictions compare very well with the experimental data and are valid not only for reduced graphene oxide but for other multilayer 2D materials, as well. [1]
