Valley-polarised tunnelling currents in bilayer graphene tunnelling transistors
J. J . P. Thompson, D. J. Leech, M. Mucha-Kruczyński
We study theoretically the electron current across a monolayer graphene/hexagonal boron nitride/bilayer graphene tunnelling junction in an external magnetic field perpendicular to…

Negative differential resistance in Van der Waals heterostructures due to moiré-induced spectral reconstruction
D. J. Leech, J. J. P. Thompson, M. Mucha-Kruczyński
Formation of moiré superlattices is common in Van der Waals heterostructures as a result of the mismatch between lattice constants and misalignment of crystallographic directions o…
