Ambient-Pressure Organic Dirac Electron State in $α$ -(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, $α$ -(BETS) $_{2}$ AuCl $_{2}$ (BETS = bis(ethylenedithio)tetraselenafulvalene). This salt exhibits char…

Surface structure of the 3x3-Si phase on Al(111), studied by the multiple usages of positron diffraction and core-level photoemission spectroscopy

Yusuke Sato, Yuki Fukaya, Akito Nakano +13

The structure of an Al(111)3x3-Si surface was examined by combining data from positron diffraction and core-level photoemission spectroscopy. Analysis of the diffraction rocking cu…
