Moiré materials have emerged as a platform for exploring the physics of strong electronic
correlations and non-trivial band topology. Here we review the recent progress in …

The fabrication of wafer-scale two-dimensional (2D) materials is a prerequisite and
important step for their industrial applications. Chemical vapor deposition (CVD) is the most …

Chern insulators, which are the lattice analogues of the quantum Hall states, can potentially
manifest high-temperature topological orders at zero magnetic field to enable next …

The pursuit of exotic phases of matter outside of the extreme conditions of a quantizing
magnetic field is a long-standing quest of solid state physics. Recent experiments have …

Quantum spin Hall (QSH) insulators are two-dimensional electronic materials that have a
bulk band gap similar to an ordinary insulator but have topologically protected pairs of edge …

The ability to control the underlying lattice geometry of a system may enable transitions
between emergent quantum ground states. We report in situ gate switching between …

Polymorphic 2D materials allow structural and electronic phase engineering, which can be
used to realize energy-efficient, cost-effective, and scalable device applications. The phase …

We predict robust Ising ferromagnetism driven by Coulomb interaction in the metallic phase
of twisted transition metal dichalcogenide homobilayers for a range of small twist angles …

Magnetic properties of materials ranging from conventional ferromagnetic metals to strongly
correlated materials such as cuprates originate from Coulomb exchange interactions. The …

Semiconductor moiré superlattices have been shown to host a wide array of interaction-
driven ground states. However, twisted homobilayers have been difficult to study in the limit …
