Report

Valley-polarised tunnelling currents in bilayer graphene tunnelling transistors

Autor: Thompson, J. J . P., Leech, D. J., Mucha-Kruczyński, M.

Publikováno v: Phys. Rev. B 99, 085420 (2019)

We study theoretically the electron current across a monolayer graphene/hexagonal boron nitride/bilayer graphene tunnelling junction in an external magnetic field perpendicular to the layers. We show that change in effective tunnelling barrier width

Report

Negative differential resistance in Van der Waals heterostructures due to moir\'{e}-induced spectral reconstruction

Autor: Leech, D. J., Thompson, J. J. P., Mucha-Kruczyński, M.

Publikováno v: Phys. Rev. Applied 10, 034014 (2018)

Formation of moir\'{e} superlattices is common in Van der Waals heterostructures as a result of the mismatch between lattice constants and misalignment of crystallographic directions of the constituent two-dimensional crystals. We discuss theoretical

Report

Controlled formation of an isolated miniband in bilayer graphene on an almost commensurate $\sqrt{3} \times \sqrt{3}$ substrate

Autor: Leech, D. J., Mucha-Kruczyński, M.

Publikováno v: Phys. Rev. B 94, 165437 (2016)

We investigate theoretically the interplay between the effects of a perpendicular electric field and incommensurability at the interface on the electronic properties of a heterostructure of bilayer graphene and a semiconducting substrate with a unit
