Two-dimensional honeycomb borophene oxide: Strong anisotropy and nodal loop transformation
Chengyong Zhong, Weikang Wu, Junjie He +5
The search for topological semimetals is mainly focused on heavy-element compounds as following the footsteps of previous research on topological insulators, with less attention on…
Quadratic and Cubic Nodal Lines Stabilized by Crystalline Symmetry
Zhi-Ming Yu, Weikang Wu, Xian-Lei Sheng +2
In electronic band structures, nodal lines may arise when two (or more) bands contact and form a one-dimensional manifold of degeneracy in the Brillouin zone. Around a nodal line,…
Three-dimensional honeycomb carbon: Junction line distortion and novel emergent fermions
Junping Hu, Weikang Wu, Chengyong Zhong +4
Carbon enjoys a vast number of allotropic forms, each possessing unique properties determined by the lattice structures and bonding characters. Here, based on first-principles calc…
Nodal Loop and Nodal Surface States in Ti3Al Family Materials
Xiaoming Zhang, Zhi-Ming Yu, Ziming Zhu +4
Topological metals and semimetals are new states of matter which attract great interest in current research. Here, based on first-principles calculations and symmetry analysis, we…
Electric Field-Tuned Topological Phase Transition in Ultra-Thin Na3Bi - Towards a Topological Transistor
James L. Collins, Anton Tadich, Weikang Wu +11
The electric field induced quantum phase transition from topological to conventional insulator has been proposed as the basis of a topological field effect transistor [1-4]. In thi…
Hybrid Structures and Strain-Tunable Electronic Properties of Carbon Nanothreads
Weikang Wu, Bo Tai, Shan Guan +2
The newly synthesized ultrathin carbon nanothreads have drawn great attention from the carbon community. Here, based on first-principles calculations, we investigate the electronic…
