Rhombohedral-stacked multilayer graphene hosts a pair of flat bands touching at zero
energy, which should give rise to correlated electron phenomena that can be tuned further …

Divergent density of states offers an opportunity to explore a wide variety of correlated
electron physics. In the thinnest limit, this has been predicted and verified in the ultraflat …

The quantum anomalous Hall (QAH) effect—a macroscopic manifestation of chiral band
topology at zero magnetic field—has been experimentally realized only by the magnetic …

Edge states of a topological insulator can be used to explore fundamental science emerging
at the interface of low dimensionality and topology. Achieving a robust conductance …

Developing alternative paradigms of electronics beyond silicon technology requires the
exploration of fundamentally new physical mechanisms, such as the valley-specific …

The realization of graphene gapped states with large on/off ratios over wide doping ranges
remains challenging. Here, we investigate heterostructures based on Bernal-stacked bilayer …

A two-dimensional electron system placed in a magnetic field develops Landau levels,
where strong Coulomb interactions lead to the appearance of many-body correlated ground …

The highly tunable band structure of the zero-energy Landau level (zLL) of bilayer graphene
makes it an ideal platform for engineering novel quantum states. However, the zero-energy …

Bernal bilayer graphene (BLG) offers a highly flexible platform for tuning the band structure,
featuring two distinct regimes. One is a tunable band gap induced by large displacement …

We study proximity-induced spin–orbit coupling (SOC) in bilayer graphene/few-layer WSe2
heterostructure devices. Contact mode atomic force microscopy (AFM) cleaning yields …
