We review the electronic properties of bilayer graphene, beginning with a description of the
tight-binding model of bilayer graphene and the derivation of the effective Hamiltonian …

As the first in a large family of 2D van der Waals (vdW) materials, graphene has attracted
enormous attention owing to its remarkable properties. The recent development of simple …

The isolation of various two-dimensional (2D) materials, and the possibility to combine them
in vertical stacks, has created a new paradigm in materials science: heterostructures based …

We report on measurements of the stiffness and breaking strength of monolayer MoS2, a
new semiconducting analogue of graphene. Single and bilayer MoS2 is exfoliated from bulk …

Electrons moving through a spatially periodic lattice potential develop a quantized energy
spectrum consisting of discrete Bloch bands. In two dimensions, electrons moving through a …

van der Waals heterostructures constitute a new class of artificial materials formed by
stacking atomically thin planar crystals. We demonstrated band structure engineering in a …

Devices made from graphene encapsulated in hexagonal boron-nitride exhibit pronounced
negative bend resistance and an anomalous Hall effect, which are a direct consequence of …

Hexagonal boron nitride (h-BN) has recently emerged as an excellent substrate for
graphene nanodevices, owing to its atomically flat surface and its potential to engineer …

Memory cells are an important building block of digital electronics. We combine here the
unique electronic properties of semiconducting monolayer MoS2 with the high conductivity …

When a crystal is subjected to a periodic potential, under certain circumstances it can adjust
itself to follow the periodicity of the potential, resulting in a commensurate state. Of particular …
