Featured Research: Hyper-honeycombs Produce Electronic Surprise

OU scientists have proposed a new family of structures called "hyper-honeycomb lattices". The atoms in those structures all posess the same planar trigonal connectivity in graphene, but are three dimensional.  In a recent publication in Physical Review Letters, Profs. Bruno Uchoa, Kieran Mullen and Dan Glatzhofer showed that those structures describe a new class of Dirac materials, which have been called "Dirac-line semimetals", and could lead to the realization…
