Controllable Quantum Spin Hall Phases in BiTe-Family van der Waals Heterobilayers
Emmanuel V. C. Lopes, Pedro H. Sophia, Felipe Crasto de Lima +1
The tunability and control of topological edge/surface states are crucial for the development of new device applications. In this work, by combining first-principles calculations a…

Engineering Quantum Phases in Two Dimensions via Vacancy-Induced Electronic Reconstruction
Emmanuel V. C. Lopes, Felipe Crasto de Lima, Caio Lewenkopf +1
Topological phases of matter are commonly understood as emerging either from crystalline symmetry and intrinsic spin-orbit coupling or from disorder-driven electronic renormalizati…

Weyl semimetal engineering by symmetry control in NiTe
Marcos G. O. Junior, Augusto L. Araújo, Emmanuel V. C. Lopes +1
In this work, we investigate the emergence of Weyl points in an inversion symmetry-breaking 1T-NiTe system. Through first-principles calculations based on the density functiona…
