Cover Story: Single-component molecular conductor and Dirac electron system are both fascinating materials, but initially, they were thought to belong to different material categories. It was a big surprise that a Fermi surface was observed in the single-component molecular crystal [Ni(tmdt)2] at the beginning of this century, because the concept of a metal seems incompatible with the concept of a molecule. On the other hand, the energy band structure of the Dirac electron system possesses a unique feature known as the Dirac cone that consists of two conical surfaces with linear dispersion meeting at a single point in momentum space. We demonstrate that the single-component molecular crystal is suitable for the formation of the Dirac cone using tight-binding models and DFT calculations. View this paper
