The possibility of triggering correlated phenomena by placing a singularity of the density of states near the Fermi energy remains an intriguing avenue toward engineering the properties of quantum materials. Twisted bilayer graphene is a key material in this regard because the superlattice produced by the rotated graphene layers introduces a van Hove singularity and flat bands near the Fermi energy...
In article number 2001656, Jyoti Katoch, Søran Ulstrup, and co‐workers apply nanoscale angle‐resolved photoemission (nanoARPES) to measure the superlattice van Hove singularity formed by the Dirac cones of twisted bilayer graphene. The photoemission experiment is performed on a device architecture that permits electrostatic tuning of the doping level, revealing the doping dependence of the singularity...
