This review presents the state of the art in strain and ripple-induced effects on the electronic
and optical properties of graphene. It starts by providing the crystallographic description of …

Generic interacting many-body quantum systems are believed to behave as classical fluids
on long time and length scales. Due to rapid progress in growing exceptionally pure crystals …

Graphene-based samples have shown a plethora of exotic characteristics and these
properties may help the realization of a new generation of fast electronic devices. However …

A wide range of materials, like d-wave superconductors, graphene, and topological
insulators, share a fundamental similarity: their low-energy fermionic excitations behave as …

Superlattices have attracted great interest because their use may make it possible to modify
the spectra of two-dimensional electron systems and, ultimately, create materials with …

The Schrödinger equation dictates that the propagation of nearly free electrons through a
weak periodic potential results in the opening of bandgaps near points of the reciprocal …

Recent progress in preparing well-controlled two-dimensional van der Waals
heterojunctions has opened up a new frontier in materials physics. Here we address the …

When atomically thin two-dimensional (2D) materials are layered, they often form
incommensurate noncrystalline structures that exhibit long-period moiré patterns when …

Graphene exhibits superior mechanical strength, high thermal conductivity, strong light–
matter interactions, and, in particular, exceptional electronic properties. These merits make …

We theoretically investigate the electronic structures of moiré superlattices arising in
monolayer/bilayer graphene stacked on hexagonal boron nitride (hBN) in the presence and …
