Overlaying two atomic layers with a slight lattice mismatch or at a small rotation angle
creates a moiré superlattice, which has properties that are markedly modified from (and at …

The advanced electrochemical properties, such as high energy density, fast charge–
discharge rates, excellent cyclic stability, and specific capacitance, make supercapacitor a …

The fractional quantum anomalous Hall effect (FQAHE), the analogue of the fractional
quantum Hall effect at zero magnetic field, is predicted to exist in topological flat bands …

Understanding the mechanism of high-transition-temperature (high-T c) superconductivity is
a central problem in condensed matter physics. It is often speculated that high-T c …

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 …

The discovery of two‐dimensional (2D) materials with unique electronic, superior
optoelectronic, or intrinsic magnetic order has triggered worldwide interest in the fields of …

Controlling the crystal structure is a powerful approach for manipulating the fundamental
properties of solids. In van der Waals materials, this control can be achieved by modifying …

The Mott insulator is a central concept in strongly correlated physics and manifests when the
repulsive Coulomb interaction between electrons dominates over their kinetic energy …

Following a significant number of graphene studies, other two‐dimensional (2D) layered
materials have attracted more and more interest for their unique structures and distinct …

The two-dimensional electron systems in graphene and in topological insulators are
described by massless Dirac equations. Although the two systems have similar …
