Twisted bilayer graphene reveals its flat bands under spin pumping
Sonia Haddad, Takeo Kato, Jihang Zhu +1
The salient property of the electronic band structure of twisted bilayer graphene (TBG), at the so-called magic angle (MA), is the emergence of flat bands around the charge neutral…
Klein tunneling in deformed honeycomb-dice lattice: from massless to massive particles
L. Mandhour, F. Bouhadida
We show that under compressive uniaxial deformation of the three-band lattice, the Dirac cones move toward each other, merge, and a gap opens, while the flat band remains u…
Magnetic Fabry-Pérot interferometer for valley filtering in a honeycomb-dice model
F. Bouhadida, L. Mandhour, S. Charfi-Kaddour
Here we theoretically investigate the valley-dependent transmission of particles through a combined electric and magnetic barrier in the model which interpolates between th…
Kohn anomaly of optical zone boundary phonons in uniaxial strained graphene: role of the electronic band structure
Sonia Haddad, Lassaad Mandhour
One of the unique properties of graphene is its extremely high mechanical strength. Several studies have shown that the mechanical failure of graphene sheet under a tensile strain…
Tunable zero-energy transmission resonances in shifted graphene bilayer
A. Daboussi, L. Mandhour, J. N. Fuchs +1
A graphene bilayer is known to perfectly reflect normally incident electrons due to their chirality. This is similar to Klein tunneling, which, in a monolayer, is instead responsib…
