Quasiparticle interference patterns in bilayer graphene with trigonal warping
Vardan Kaladzhyan, Frédéric Joucken, Zhehao Ge +5
We calculate the form of quasiparticle interference patterns in bilayer graphene within a low-energy description, taking into account perturbatively the trigonal warping terms. We…
Surface states and quasiparticle interference in Bernal and rhombohedral graphite with and without trigonal warping
Vardan Kaladzhyan, Sarah Pinon, Frédéric Joucken +6
We use an exact analytical technique [Phys. Rev. B \textbf{101}, 115405 (2020), Phys. Rev. B \textbf{102}, 165117 (2020)] to recover the surface Green's functions for Bernal (ABA)…
Sublattice dependence and gate-tunability of midgap and resonant states induced by native dopants in Bernal-stacked bilayer graphene
Frédéric Joucken, Cristina Bena, Zhehao Ge +5
The properties of semiconductors can be crucially impacted by midgap states induced by dopants, which can be native or intentionally incorporated in the crystal lattice. For Bernal…
Direct Visualization of Native Defects in Graphite and Their Effect on the Electronic Properties of Bernal-Stacked Bilayer Graphene
Frederic Joucken, Cristina Bena, Zhehao Ge +7
Graphite crystals used to prepare graphene-based heterostructures are generally assumed to be defect free. We report here scanning tunneling microscopy results that show graphite c…
