Substrate, temperature and magnetic field dependence of electric polarisation in mixed-stacking tetralayer graphenes
Patrick Johansen Sarsfield, Aitor Garcia-Ruiz, Vladimir I. Fal'ko
Polytypes of tetralayer graphene (TLG: Bernal, rhombohedral and mixed stacking) are crystalline structures with different symmetries. Among those, mixed-stacking tetralayers lack i…
Mixed-Stacking Few-Layer Graphene as an Elemental Weak Ferroelectric Material
Aitor Garcia-Ruiz, Vladimir Enaldiev, Andrew McEllistrim +1
Ferroelectricity (Valasek, J. Phys. Rev. 1921, 17, 475) - a spontaneous formation of electric polarisation - is a solid state phenomenon, usually, associated with ionic compounds o…
ARPES signatures of few-layer twistronic graphenes
J. E. Nunn, A. McEllistrim, A. Weston +7
Diverse emergent correlated electron phenomena have been observed in twisted graphene layers due to electronic interactions with the moiré superlattice potential. Many electronic s…
Kagomé quantum oscillations in graphene superlattices
Folkert K. de Vries, Sergey Slizovskiy, Petar Tomić +12
Periodic systems feature the Hofstadter butterfly spectrum produced by Brown--Zak minibands of electrons formed when magnetic field flux through the lattice unit cell is commensura…
Spectroscopic signatures of tetralayer graphene polytypes
Andrew McEllistrim, Aitor Garcia-Ruiz, Zachary A. H. Goodwin +1
Tetralayer graphene has recently become a new addition to the family of few-layer graphene with versatile electronic properties. This material can be realised in three distinctive…
Flat bands for electrons in rhombohedral graphene multilayers with a twin boundary
Aitor Garcia-Ruiz, Sergey Slizovskiy, Vladimir I. Fal'ko
Topologically protected flat surface bands make thin films of rhombohedral graphite an appealing platform for searching for strongly correlated states of 2D electrons. In this work…
Band Gap Opening in Bilayer Graphene-CrCl/CrBr/CrI van der Waals Interfaces
Giulia Tenasini, David Soler-Delgado, Zhe Wang +10
We report experimental investigations of transport through bilayer graphene (BLG)/chromium trihalide (CrX; X=Cl, Br, I) van der Waals interfaces. In all cases, a large charge t…
Scattering between minivalleys in a moiré material
Petar Tomić, Peter Rickhaus, Aitor Garcia-Ruiz +8
A unique feature of the complex band structures of moiré materials is the presence of minivalleys, their hybridization, and scattering between them. Here we investigate magneto-tra…
Full Slonczewski-Weiss-McClure parametrization of few-layer twistronic graphene
Aitor Garcia-Ruiz, Haiyao Deng, Vladimir V. Enaldiev +1
We use a hybrid k dot p theory - tight binding (HkpTB) model to describe interlayer coupling simultaneously in both Bernal and twisted graphene structures. For Bernal-aligned inter…
Coherent Jetting behind a gate-defined Channel in Bilayer Graphene
Carolin Gold, Angelika Knothe, Annika Kurzmann +6
Graphene has evolved as a platform for quantum transport that can compete with the best and cleanest semiconductor systems. Recently, many interesting local properties of carrier t…
Electronic Raman Scattering in Twistronic Few-Layer Graphene
A. Garcia-Ruiz, J. J. P. Thompson, M. Mucha-Kruczynski +1
We study electronic contribution to the Raman scattering signals of two-, three- and four-layer graphene with layers at one of the interfaces twisted by a small angle with respect…
Tunable van Hove Singularities and Correlated States in Twisted Trilayer Graphene
Yanmeng Shi, Shuigang Xu, Mohammed M. Al Ezzi +16
Understanding and tuning correlated states is of great interest and significance to modern condensed matter physics. The recent discovery of unconventional superconductivity and Mo…

We describe how the out-of-plane dielectric polarizability of monolayer graphene influences the electrostatics of bilayer graphene -- both Bernal (BLG) and twisted (tBLG). We compa…
