Journal ArticleDOI
Peierls distortion as a route to high thermoelectric performance in In4Se3―δ crystals
Jong-soo Rhyee,Kyu Hyoung Lee,Sang Mock Lee,Eunseog Cho,Sang-Il Kim,Eun-sung Lee,Yong Seung Kwon,Ji Hoon Shim,Gabriel Kotliar +8 more
TL;DR: A binary crystalline n-type material, In4Se3-δ, is reported, which achieves the ZT value of 1.48 at 705 K—very high for a bulk material and suggests a new direction in the search for high-performance thermoelectric materials, exploiting intrinsic nanostructural bulk properties induced by charge density waves.
Journal ArticleDOI
Correlated electronic structure of LaO1-xFxFeAs.
TL;DR: The electronic structure, momentum resolved spectral function and optical conductivity of the new superconductor LaO1-xFxFeAs are computed and it is argued that the superconductivity is not phonon mediated.
Journal ArticleDOI
Large anomalous Hall current induced by topological nodal lines in a ferromagnetic van der Waals semimetal.
Kyoo Kim,Junho Seo,Eunwoo Lee,Kyung-Tae Ko,Byung-Ho Kim,Bo Gyu Jang,Jong Mok Ok,Jinwon Lee,Younjung Jo,Woun Kang,Ji Hoon Shim,Changyoung Kim,Han Woong Yeom,Byung Il Min,Bohm-Jung Yang,Jun Sung Kim +15 more
TL;DR: A combined experimental and theoretical approach identifies the van der Waals material Fe3GeTe2 as a candidate ferromagnetic nodal line semimetal and extends the connections between topology and magnetism.
Journal ArticleDOI
Fluctuating valence in a correlated solid and the anomalous properties of delta-plutonium.
TL;DR: In this article, the authors identify the electronic mechanisms responsible for the anomalous behavior of late actinides, revisiting the concept of valence using a theoretical approach that treats magnetism, Kondo screening, atomic multiplet effects and crystal field splitting on the same footing.
Journal ArticleDOI
Anisotropic Dirac fermions in a Bi square net of SrMnBi2
Joonbum Park,Geunsik Lee,Frederik Wolff-Fabris,Yoonyoung Koh,Man Jin Eom,Yeongkwan Kim,M. A. Farhan,Younjung Jo,Chol Kim,Ji Hoon Shim,Jun Sung Kim +10 more
TL;DR: These findings demonstrate that a Bi square net, a common building block of various layered pnictides, provides a new platform that hosts highly anisotropic Dirac fermions.
