We calculate theoretically the disorder-limited conductivity of monolayer and bilayer graphene on hexagonal boron nitride (h-BN) substrates, comparing our theoretical results with the recent experimental results. The comparison leads to a direct quantitative estimate of the underlying disorder strength for both short- and long-range disorder in the graphene on the h-BN system. We find that the good interface quality between graphene and h-BN leads to strongly suppressed charged impurity…

Multiscale modeling of screening effects on conductivity of graphene in weakly bonded graphene-dielectric heterostructures

Graphene is often surrounded by different dielectric materials when integrated into realistic devices. The absence of dangling bonds allows graphene to bond weakly via the van der Waals interaction

Advances in 2D boron nitride nanostructures: nanosheets, nanoribbons, nanomeshes, and hybrids with graphene.

The structural basics, spectroscopic signatures, and physical properties of the 2D BN nanostructures are discussed and various top-down and bottom-up preparation methodologies are reviewed in detail.

Inter-layer potential for hexagonal boron nitride.

The new force-field contains three terms representing the interlayer attraction due to dispersive interactions, repulsion due to anisotropic overlaps of electron clouds, and monopolar electrostatic interactions and allows for the accurate and efficient modeling and simulation of large-scale h-BN based layered structures.
