Electronic Origins of Large Thermoelectric Power Factor of LaOBiS2-xSex
Atsuhiro Nishida, Hirotaka Nishiate, Chul-Ho Lee +2
We examined the electrical transport properties of densified LaOBiS2-xSex, which constitutes a new family of thermoelectric materials. The power factor increased with increasing co…
Superconductivity phase diagram of Se-substituted CeO0.5F0.5Bi(S1-xSex)2
Yoshikazu Mizuguchi, Takafumi Hiroi, Osuke Miura
We investigated the effects of Se substitution on the lattice constants and superconducting properties of CeO0.5F0.5Bi(S1-xSex)2. With increasing Se concentration, the a lattice co…
High thermoelectric performance and low thermal conductivity of densified LaOBiSSe
Atsuhiro Nishida, Osuke Miura, Chul-Ho Lee +1
In this study, we examined the thermoelectric properties of the layered bismuth-chalcogenide-based (BiCh2-based) compound LaOBiSSe, which is expected to be a new candidate material…
Pronounced - Log T Divergence in Specific Heat of Nonmetallic CeOBiS: A Mother Phase of BiS-Based Superconductor
Ryuji Higashinaka, Takuya Asano, Takuya Nakashima +5
The low-temperature properties of CeOBiS single crystals are studied by electrical resistivity, magnetization, and specific heat measurements. Ce 4f -electrons are found to be…
In-plane chemical pressure essential for superconductivity in BiCh2-based (Ch: S, Se) layered structure
Yoshikazu Mizuguchi, Akira Miura, Joe Kajitani +7
BiCh2-based superconductors (Ch: S, Se) are a new series of layered superconductor. However, mechanisms for the emergence of superconductivity in BiCh2-based superconductors have n…
In-plane Charge Fluctuations in Bismuth Sulfide Superconductors
Anushika Athauda, Junjie Yang, Seunghun Lee +5
Evidence for local charge fluctuations linked to a charge disproportionation of the Bi ions in the distorted lattice of superconducting LaOF BiS is presented. I…
