This is an update of a previous review (Naumis et al 2017 Rep. Prog. Phys. 80 096501).
Experimental and theoretical advances for straining graphene and other metallic, insulating …

For solid-state materials, the electronic structure is critical in determining a crystal's physical
properties. By experimentally detecting the electronic structure, the fundamental physics can …

Revealing the fine electronic structure is critical for understanding the underlying physics of
low-dimensional materials. Angle-resolved photoemission spectroscopy (ARPES) is a …

Controlling the interlayer coupling in two-dimensional (2D) materials generates novel
electronic and topological phases. Its effective implementation is commonly done with a …

Superlattice potentials imposed on graphene can alter its Dirac states, enabling the
realization of various quantum phases. We report the experimental observation of a replica …

The metal-intercalated bilayer graphene has a flat band with a high density of states near
the Fermi energy and thus is anticipated to exhibit an enhanced strong correlation effect and …

Realizing Von Hove singularity (VHS) and extended flat bands of graphene near the Fermi
level (EF) is of great significance to explore many-body interactions, with a high tendency …

In graphene, a Kekulé-Y bond texture modifies the electronic band structure, generating two
concentric Dirac cones with different Fermi velocities lying in the Γ point in reciprocal space …

The existence of superconductivity (SC) appears to be established in both twisted and
nontwisted graphene multilayers. However, whether their building block, single-layer …

We report the observation of graphene doped up to the Lifshitz transition obtained solely by
the intercalation of Erbium atoms. ARPES measurements show that a wide flat band is …
