Flat bands and gaps in twisted double bilayer graphene
F. J. Culchac, Rodrigo B. Capaz, Leonor Chico +1
We present electronic structure calculations of twisted double bilayer graphene (TDBG): A tetralayer graphene structure composed of two AB-stacked graphene bilayers with a relative…
Strain-induced phase transition in CrI bilayers
Andrea Leon, J. W. González, J. Mejía-López +2
A monolayer of CrI is a two-dimensional crystal that in its equilibrium configuration is a ferromagnetic semiconductor, however, two coupled layers can be ferromagnetic or anti…
One-way transport in laser-illuminated bilayer graphene: A Floquet isolator
Virginia Dal Lago, Eric Suárez Morell, Luis E. F. Foa Torres
We explore the Floquet band-structure and electronic transport in laser-illuminated bilayer graphene. By using a bias voltage perpendicular to the graphene bilayer we show how to g…
Twisted bilayer blue phosphorene: A direct band gap semiconductor
D. A. Ospina, C. A. Duque, J. D. Correa +1
We report that two rotated layers of blue phosphorene behave as a direct band gap semiconductor. The optical spectrum shows absorption peaks in the visible region of the spectrum a…
Crafting zero-bias one-way transport of charge and spin
L. E. F. Foa Torres, V. Dal Lago, E. Suárez Morell
We explore the electronic structure and transport properties of a metal on top of a (weakly coupled) two-dimensional topological insulator. Unlike the widely studied junctions betw…
Periodic arrays of intercalated atoms in twisted bilayer graphene: an \it{ ab initio} investigation
R. H. Miwa, P. Venezuela, E. Suárez Morell
We have performed an \it {ab initio} investigation of transition metals (TMs = Mo, Ru, Co, and Pt) embedded in twisted bilayer graphene (tBG) layers. Our total energy results revea…
