Orbital Multiferroicity in Pentalayer Rhombohedral Graphene

Tonghang Han, Zhengguang Lu, Giovanni Scuri +8

Ferroic orders describe spontaneous polarization of spin, charge, and lattice degrees of freedom in materials. Materials featuring multiple ferroic orders, known as multiferroics,…

Correlated Insulator and Chern Insulators in Pentalayer Rhombohedral Stacked Graphene

Tonghang Han, Zhengguang Lu, Giovanni Scuri +7

Rhombohedral stacked multilayer graphene is an ideal platform to search for correlated electron phenomena, due to its pair of flat bands touching at zero energy and further tunabil…

Spectroscopy Signatures of Electron Correlations in a Trilayer Graphene/hBN Moiré Superlattice

Jixiang Yang, Guorui Chen, Tianyi Han +12

ABC-stacked trilayer graphene/hBN moiré superlattice (TLG/hBN) has emerged as a playground for correlated electron physics. We report spectroscopy measurements of dual-gated TLG/hB…

Weyl Fermion Magneto-Electrodynamics and Ultra-low Field Quantum Limit in TaAs

Zhengguang Lu, Patrick Hollister, Mykhaylo Ozerov +6

Topological semimetals are predicted to exhibit unconventional electrodynamics, but a central experimental challenge is singling out the contributions from the topological bands. T…

Accurate Measurement of the Gap of Graphene/hBN Moiré Superlattice through Photocurrent Spectroscopy

Tianyi Han, Jixiang Yang, Qihang Zhang +5

Monolayer graphene aligned with hexagonal boron nitride (hBN) develops a gap at the charge neutrality point (CNP). This gap has previously been extensively studied by electrical tr…

Characterization and manipulation of individual defects in insulating hexagonal boron nitride using scanning tunneling microscopy

Dillon Wong, Jairo Velasco, Long Ju +9

Defects play a key role in determining the properties of most materials and, because they tend to be highly localized, characterizing them at the single-defect level is particularl…

Gate-dependent Pseudospin Mixing in Graphene/Boron Nitride Moire Superlattices

Zhiwen Shi, Chenhao Jin, Wei Yang +13

Electrons in graphene are described by relativistic Dirac-Weyl spinors with a two-component pseudospin1-12. The unique pseudospin structure of Dirac electrons leads to emerging phe…
