In this talk I will introduce some basic chemical concepts about electron
counting and bonding to show how they can be used as a guiding tools to
discover new Dirac Semimetals. I will show how I used these principles to
identify several materials of interest for Dirac physics. I will introduce the
material Au2Pb, which is a superconducting Dirac semimetal, Ca3P2 a line node
material and ZrSiS, which is the Dirac semimetal with the largest energy range
of linearly dispersed bands. Lastly I will introduce a chemists view about
Dirac materials that result form non-symmorphic symmetry. I will show how we
used chemical concepts to experimentally verify a fourfold degenerate point at
the Fermi level in ZrSiTe.
