Query: Visualizing the Effect of an Electrostatic Gate with Angle-Resolved
  Photoemission Spectroscopy   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 photoemission spectroscopy (ARPES), the technique of choice to
non-invasively probe the electronic band structure of a material. By means of a
state-of-the-art ARPES setup with sub-micron spatial resolution, we have
investigated a heterostructure composed of Bernal-stacked bilayer graphene
(BLG) on hexagonal boron nitride and deposited on a graphite flake. By voltage
biasing the latter, the electric field effect is directly visualized on the
valence band as well as on the carbon 1s core level of BLG. The band gap
opening of BLG submitted to a transverse electric field is discussed and the
importance of intralayer screening is put forward. Our results pave the way for
new studies that will use momentum-resolved electronic structure information to
gain insight on the physics of materials submitted to the electric field
effect.
