Interface states at the boundary between ABC and ABA multilayer graphene structures
Maxence Grandadam, Sarah Pinon, Cristina Bena +1
We study the interfaces between ABC and ABA regions in multilayer graphene, in particular we consider regions in which the transition between the ABA and ABC structure arises due t…
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)…
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…
Surface Green's functions and quasiparticle interference in Weyl semimetals
Sarah Pinon, Vardan Kaladzhyan, Cristina Bena
We use the exact analytical technique introduced in Phys. Rev. B 101, 115405 to recover the surface Green's functions and the corresponding Fermi-arc surface states for various lat…
Exact lattice-model calculation of boundary modes for Weyl semimetals and graphene
Vardan Kaladzhyan, Sarah Pinon, Jens H. Bardarson +1
We provide an exact analytical technique to obtain within a lattice model the wave functions of the edge states in zigzag- and bearded-edge graphene, as well as of the Fermi-arc su…
Modeling long imperfect SNS junctions and Andreev bound states using two impurities and the T -matrix formalism
Sarah Pinon, Vardan Kaladzhyan, Cristina Bena
We provide a new analytical tool to calculate the energies of Andreev bound states (ABS) in long imperfect SNS junctions, at present these can only be described by numerical tools.…
