The unusual electronic properties of graphene, which are a direct consequence of its two-
dimensional honeycomb lattice, have attracted a great deal of attention in recent years …

The so-called artificial graphene is an artificial material whose low-energy carriers are
described by the massless Dirac equation. Applying a periodic potential with triangular …

Recent advances in the creation and modulation of graphenelike systems are introducing a
science of “designer Dirac materials”. In its original definition, artificial graphene is a man …

Charge carriers in graphene behave like massless Dirac fermions (MDFs) with linear energy-
momentum dispersion,, providing a condensed-matter platform for studying quasiparticles …

At low energy, electrons in doped graphene sheets behave like massless Dirac fermions
with a Fermi velocity, which does not depend on carrier density. Here we show that …

We demonstrate that Dirac fermions can be created and manipulated in a two-dimensional
electron gas (2DEG). Using a cryogenic scanning tunneling microscope, we arranged …

Engineered honeycomb lattices, called artificial graphene (AG), are tunable platforms for the
study of novel electronic states related to Dirac physics. In this work, we report the …

Artificial lattices provide a tunable platform to realize exotic quantum devices. A well-known
example is artificial graphene (AG), in which electrons are confined in honeycomb lattices …

Recently, new materials exhibiting exotic band structures characterized by Dirac cones,
nontrivial flat bands, and band crossing points have been proposed on the basis of effective …
