Ambient-Pressure Organic Dirac Electron State in $I^\pm$ -(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, $I^\pm$ -(BETS) $_{2}$ AuCl $_{2}$ (BETS = bis(ethylenedithio)tetraselenafulvalene). This salt exhibits cha…

Combined X-ray diffraction, electrical resistivity, and $ab$ $ini t i o$ study of (TMTTF) $_{2}$ PF $_{6}$ under pressure: implications to the unified phase diagram

Miho Itoi, Kazuyoshi Yoshimi, Hanming Ma +7

We present a combined experimental and theoretical study on the quasi-one-dimensional organic conductor (TMTTF) $_{2}$ PF $_{6}$ , and elucidate the variation of its physical properties un…

Pressure-induced topological changes in Fermi surface of two-dimensional molecular conductor

T. Kobayashi, K. Yoshimi, H. Ma +5

We demonstrated X-ray structural analysis of the pressure-induced superconductor, $Î²'$-ET $_{2}$ ICl $_{2}$ under extremely high-pressure conditions, where ET denotes bis(ethylenedithio)…

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…
