Borophene, a 2D allotrope of boron and the lightest elemental Dirac material, is the latest
very promising 2D material owing to its unique structural and electronic characteristics of the …

Since the discovery of buckminsterfullerene over 30 years ago, sp2-hybridised carbon
nanomaterials (including fullerenes, carbon nanotubes, and graphene) have stimulated new …

Recent experiments show how a bilayer graphene twisted around a certain magic angle
becomes superconducting as it is doped into a region with approximate flat bands. We …

Superconductivity in two-dimensional compounds is widely studied, not only because of its
application in constructing nano-superconducting devices, but also for general scientific …

This tutorial review presents an overview of the basic theoretical aspects of two-dimensional
(2D) crystals. We revise essential aspects of graphene and the new families of …

Recent progress in two-dimensional superconductors with atomic-scale thickness is
reviewed mainly from the experimental point of view. The superconducting systems treated …

Operando microbeam Raman spectroscopy is used to map the changes in hard carbon
during sodiation and desodiation in unprecedented detail, elucidating several important and …

Borophene, a crystalline allotrope of monolayer boron, with a combination of triangular
lattice and hexagonal holes, has stimulated wide interest in 2-dimensional materials and …

We report a first-principles investigation of electronic structure, topological bands, and
electron-phonon interactions in metallic biphenylene sheets. Biphenylene is a recently …

We present measurements of the superconducting and charge-density-wave (CDW) critical
temperatures (T c and T CDW) as a function of pressure in the transition metal …
