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…
Stacking-induced Chern insulator
Marwa Mannaï, Jean-Noël Fuchs, Frédéric Piéchon +1
Graphene can be turned into a semimetal with broken time-reversal symmetry by adding a valley-dependent pseudo-scalar potential that shifts the Dirac point energies in opposite dir…
Twistronics versus straintronics in twisted bilayers of graphene and transition metal dichalcogenides
Marwa Mannaï, Sonia Haddad
Several numerical studies have shown that the electronic properties of twisted bilayers of graphene (TBLG) and transition metal dichalcogenides (TMDs) are tunable by strain enginee…
Strain tuned topology in the Haldane and the modified Haldane models
Marwa Mannaï, Sonia Haddad
We study the interplay between a uniaxial strain and the topology of the Haldane and the modified Haldane models which, respectively, exhibit chiral and antichiral edge modes. The…
Electron-phonon dynamics in 2D carbon based-hybrids XC (X = Si, Ge, Sn)
L. B. Drissi, N. B-J. Kanga, S. Lounis +2
The effect of the presence of electron-phonon (e-ph) coupling in the SiC, GeC and SnC hybrids is studied in the framework of the ab initio perturbation theory. The electronic bang…
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…
