Strong and Tunable Electrical-Anisotropy in Type-II Weyl Semimetal Candidate WP2 with Broken Inversion Symmetry
Bo Su, Yanpeng Song, Yanhui Hou +7
A transition metal diphosphide WP2 is a candidate for type-II Weyl semimetals (WSMs) in which spatial inversion symmetry is broken and Lorentz invariance is violated. As one of the…
Persistence of Monoclinic Crystal Structure in Three-Dimensional Second-Order Topological Insulator Candidate 1T'-MoTe2 Thin Flake without Structural Phase transition
Bo Su, Yuan Huang, Yan Hui Hou +8
A van der Waals material, MoTe2 with a monoclinic 1T' crystal structure is a candidate for three-dimensional (3D) second-order topological insulators (SOTIs) hosting gapless hinge…
Tightly-bound and room-temperature-stable excitons in van der Waals degenerate-semiconductor Bi4O4SeCl2 with high charge-carrier density
Yueshan Xu, Junjie Wang, Bo Su +9
Excitons, which represent a type of quasi-particles consisting of electron-hole pairs bound by the mutual Coulomb interaction, were often observed in lowly-doped semiconductors or…
Electronic correlations and flattened band in magnetic Weyl semimetal candidate Co3Sn2S2
Yueshan Xu, Jianzhou Zhao, Changjiang Yi +13
The interplay between electronic correlations and topological protection may offer a rich avenue for discovering emergent quantum phenomena in condensed matter. However, electronic…
Two-dimensional Massless Dirac Fermions in Antiferromagnetic AFe2As2 (A = Ba, Sr)
Zhi-Guo Chen, Luyang Wang, Yu Song +7
We report infrared studies of AFeAs (A = Ba, Sr), two representative parent compounds of iron-arsenide superconductors, at magnetic fields (B) up to 17.5 T. Optical tra…
Observation of an intrinsic bandgap and Landau level renormalization in graphene/boron-nitride heterostructures
Zhi-Guo Chen, Zhiwen Shi, Wei Yang +6
Van der Waals heterostructures formed by assembling different two-dimensional atomic crystals into stacks can lead to many new phenomena and device functionalities. In particular,…
Persistent high-energy spin excitations in iron pnictide superconductors
K. J. Zhou, Y. B. Huang, C. Monney +10
Motivated by the premise that superconductivity in iron-based superconductors is unconventional and mediated by spin fluctuations, an intense research effort has been focused on ch…
