The enabling electronic motif for topological insulation in ABO3 perovskites and its structural stability
Xiuwen Zhang, Leonardo B. Abdalla, Qihang Liu +1
Stable oxide topological insulators (TIs) that could bring together the traditional oxide functionalities with the dissipationless surface states of TIs have been sought for years…
Predicted Realization of Cubic Dirac Fermion in Quasi-One-Dimensional Transition-Metal MonoChalcogenides
Qihang Liu, Alex Zunger
We show that the previously predicted Fermion particle that has no analogue in the standard model of particle theory - the cubically dispersed Dirac semimetal (CDSM) - is realized…
Minimal Ingredients for Orbital Texture Switches at Dirac Points in Strong Spin-Orbit Coupled Materials
J. A. Waugh, T. Nummy, S. Parham +4
Recent angle resolved photoemission spectroscopy measurements on strong spin-orbit coupled materials have shown an in-plane orbital texture switch at their respective Dirac points,…
Orbital mapping of energy bands and the truncated spin polarization in three-dimensional Rashba semiconductors
Qihang Liu, Xiuwen Zhang, J. A. Waugh +2
Associated with spin-orbit coupling (SOC) and inversion symmetry breaking, Rashba spin polarization opens a new avenue for spintronic applications that was previously limited to or…
Predicted electronic markers for polytypes of LaOBiS2 examined via angular resolved photoemission spectroscopy
Xiaoqing Zhou, Qihang Liu, J. A. Waugh +7
The natural periodic stacking of symmetry-inequivalent planes in layered compounds can lead to the formation of natural superlattices; albeit close in total energy, (thus in their…
Transforming common III-V and II-VI semiconductor compounds into topological heterostructures: The case of CdTe/InSb superlattices
Qihang Liu, Xiuwen Zhang, L. B. Abdalla +1
Currently known topological insulators (TIs) are limited to narrow gap compounds incorporating heavy elements, thus severely limiting the material pool available for such applicati…
