Designer gapped and tilted Dirac cones in lateral graphene superlattices
A. Wild, R. R. Hartmann, E. Mariani +1
We show that a planar array of bipolar waveguides in graphene can be used to engineer gapped and tilted two-dimensional Dirac cones within the electronic band structure. The presen…
Valley separation of photoexcited carriers in bilayer graphene
T. J. Osborne, M. E. Portnoi, E. Mariani
We derive the angular generation density of photoexcited carriers in gapless and gapped Bernal bilayer graphene. Exploiting the strong anisotropy of the band structure of bilayer g…
Tunable mechanically-induced hysteresis in suspended Josephson junctions
Jamie Le Signe, Thomas McDermott, Eros Mariani
The coupling of superconducting systems to mechanical resonators is an emerging field, with wide reaching implications including high precision sensing and metrology. Experimental…
Optical valley separation in two-dimensional semimetals with tilted Dirac cones
A. Wild, E. Mariani, M. E. Portnoi
Two-dimensional semimetals with tilted Dirac cones in the electronic band structure are shown to exhibit spatial separation of carriers belonging to different valleys under illumin…
Optical absorption in two-dimensional materials with tilted Dirac cones
A. Wild, E. Mariani, M. E. Portnoi
The interband optical absorption of linearly polarised light by two-dimensional (2D) semimetals hosting tilted and anisotropic Dirac cones in the bandstructure is analysed theoreti…
Josephson junctions as nanoelectromechanical Bloch oscillators
T. McDermott, E. Mariani, H. Deng
Bloch oscillations were predicted and observed long ago in Josephson junctions, which are thin insulating or conducting layers bridging two superconductors. Here we forward a schem…
