Dirac cones, named after the renowned physicist Paul Dirac, are unique features found in the electronic band structures of certain materials, such as graphene and topological insulators. These cones ...
Raman spectroscopy experiments show that the interaction between electrons and phonons in graphene resembles the Dirac fermion–photon coupling in quantum electrodynamics. In the early days of ...
To address the challenges, this research introduces a paradigm-shifting method of band engineering by creating an artificial kagome superlattice to manipulate the Dirac bands in graphene.
As a result, an emergent honeycomb connectivity arises formally equivalent to the well-known graphene. At the same time ... may exhibit unique electronic properties, such as a Dirac cone band ...
