Ambient-Pressure Organic Dirac Electron State in $\alpha$-(BETS)${}_2$AuCl${}_2$

Takuya Kobayashi, Kazuyoshi Yoshimi, Aoto Nishimoto +2

We report an ambient-pressure Dirac electron (DE) state in a new organic conductor, $\alpha$-(BETS)${}_2$AuCl${}_2$ (BETS = bis(ethylenedithio)tetraselenafulvalene). This salt exhibits char…
