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…
Probing the Electronic Structure of Graphene Near and Far from the Fermi Level via Planar Tunneling Spectroscopy
John L. Davenport, Zhehao Ge, Junyan Liu +12
Scanning tunneling spectroscopy (STS) has yielded significant insight on the electronic structure of graphene and other two-dimensional (2D) materials. STS directly measures a fund…
Visualizing the Effect of an Electrostatic Gate with Angle-Resolved Photoemission Spectroscopy
Frédéric Joucken, Jose Avila, Zhehao Ge +9
Electrostatic gating is pervasive in materials science, yet its effects on the electronic band structure of materials has never been revealed directly by angle-resolved photoemissi…
