Covalent organic frameworks (COFs) are an emerging type of porous crystalline polymers
that are built by light elements (typically H, B, C, N, O and Si) via organic covalent bonds …

Van der Waals heterostructures form a unique class of layered artificial solids in which
physical properties can be manipulated through controlled composition, order and relative …

Ultraflatbands in twisted bilayers of two-dimensional materials have the potential to host
strong correlations, including the Mott-insulating phase at half-filling of the band. Using first …

We introduce configuration space as a natural representation for calculating the mechanical
relaxation patterns of incommensurate two-dimensional (2D) bilayers. The approach can be …

Light-based neuromodulation systems offer exceptional spatiotemporal resolution combined
with the elimination of physical tether to communicate with neurons. Currently, optical …

When oppositely charged polymers are mixed, counterion release drives phase separation;
understanding this process is a key unsolved problem in polymer science and biophysical …

Valley pseudospin, labeling the pair of energy extrema in momentum space, has been
attracting attention because of its potential as a new degree of freedom in manipulating …

Abstract Two-dimensional (2D) materials exhibit enhanced physical, chemical, electronic,
and optical properties when compared to those of bulk materials. Graphene demands …

Graphene quantum dots (GQDs) not only have potential applications on spin qubit, but also
serve as essential platforms to study the fundamental properties of Dirac fermions, such as …
