Journal ArticleDOI
Nodal surface semimetals: Theory and material realization
Weikang Wu,Ying Liu,Si Li,Si Li,Chengyong Zhong,Zhi-Ming Yu,Xian-Lei Sheng,Xian-Lei Sheng,Y. X. Zhao,Shengyuan A. Yang +9 more
TL;DR: In this paper, the authors theoretically study the three-dimensional topological semimetals with nodal surfaces protected by crystalline symmetries, and they show that in the presence of spin-orbit coupling (SOC), the conduction and valence bands cross on closed nodal surface in the Brillouin zone.
Journal ArticleDOI
Electric-field-tuned topological phase transition in ultrathin Na3Bi.
James L. Collins,Anton Tadich,Anton Tadich,Weikang Wu,Lídia C. Gomes,Lídia C. Gomes,J. N. B. Rodrigues,J. N. B. Rodrigues,Chang Liu,Jack Hellerstedt,Jack Hellerstedt,Hyejin Ryu,Hyejin Ryu,Shujie Tang,Sung-Kwan Mo,Shaffique Adam,Shaffique Adam,Shengyuan A. Yang,Shengyuan A. Yang,Michael S. Fuhrer,Mark T. Edmonds +20 more
TL;DR: The large bandgaps in both the conventional and quantum spin Hall phases, much greater than the thermal energy at room temperature, suggest that ultrathin Na3Bi is suitable for room-temperature topological transistor operation.
Journal ArticleDOI
Spin-momentum locking and spin-orbit torques in magnetic nano-heterojunctions composed of Weyl semimetal WTe 2
Peng Li,Weikang Wu,Yan Wen,Chenhui Zhang,Junwei Zhang,Senfu Zhang,Zhi-Ming Yu,Shengyuan A. Yang,Aurelien Manchon,Xixiang Zhang +9 more
TL;DR: A significantly enhanced spin conductivity is observed, which is associated with the field-like torque at low temperatures, which can be ascribed to the enhanced spin accumulation by the spin–momentum locking effect of the Fermi arcs of the Weyl semimetal WTe2.
Journal ArticleDOI
Nodal loop and nodal surface states in the Ti 3 Al family of materials
Xiaoming Zhang,Xiaoming Zhang,Zhi-Ming Yu,Ziming Zhu,Weikang Wu,Shan-Shan Wang,Xian-Lei Sheng,Shengyuan A. Yang +7 more
TL;DR: In this article, the authors show that the titanium-based compounds have an almost ideal nodal loop in the sense that the loop is close to the Fermi level and it is nearly flat in energy with energy variation $l 0.25$ meV.
Journal ArticleDOI
Valley-dependent properties of monolayer MoSi 2 N 4 , WSi 2 N 4 , and MoSi 2 As 4
Si Li,Si Li,Weikang Wu,Xiaolong Feng,Shan Guan,Wanxiang Feng,Yugui Yao,Shengyuan A. Yang,Shengyuan A. Yang +8 more
TL;DR: Hong et al. as mentioned in this paper investigated the electronic and optical properties of monolayer semiconductors with a pair of Dirac-type valleys located at the corners of the hexagonal Brillouin zone.
