Locally resolved electronic textures of reconstruction domains in marginally twisted monolayer-bilayer graphene
Sean M. Walker, Patrick Sarsfield, Isaac Soltero +7
Controlling the stacking and rotational registry of graphene layers provides a powerful handle on atomic-scale structural reconstructions that alter the electronic landscape at the…
Resonant Structure of Second Harmonic Generation in Multilayer Graphene Polytypes
Patrick Johansen Sarsfield, Takaaki V. Joya, Takuto Kawakami +2
Second harmonic generation (SHG) is a powerful optical tool for identifying non-centrosymmetric crystalline structures. Here, we analyze SHG in multilayer graphenes (MLG), with a f…
Stacking-induced ferroelectricity in tetralayer graphene
Amit Singh, Shuigang Xu, Patrick Johansen Sarsfield +12
Recent studies have reported emergent ferroelectric behavior in twisted or moiré-engineered graphene-based van der Waals heterostructures, yet the microscopic origin of this effec…
Electronic properties of stacking faults in Bernal graphite
Patrick Johansen Sarsfield, Sergey Slizovskiy, Mikito Koshino +1
Using the tight-binding model of graphite, incorporating all Slonczewski-Weiss-McClure parameters, we compute the spectrum of two-dimensional states of electrons bound to a stackin…
