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…
Interacting Virtual Topological Phases in Defect-Rich 2D Materials
Felipe Crasto de Lima, Roberto H. Miwa, Caio Lewenkopf +1
We investigate the robustness of {\it virtual} topological states -- topological phases away from the Fermi energy -- against the electron-electron interaction and band filling. As…
Reentrant topological phase in half-Heusler compounds
Augusto L. Araújo, Felipe Crasto de Lima, Adalberto Fazzio
Half-Heusler compounds are known for their various compositions and multifunctional properties including topological phases. In this study, we investigate the topological classific…
Unraveling the Spin-to-Charge Current Conversion Mechanism and Charge Transfer Dynamics at Interface of Graphene/WS Heterostructures at Room Temperature
Rafael O. Cunha, Yunier Garcia-Basabe, Dunieskys G. Larrude +7
We report experimental investigations of spin-to-charge current conversion and charge transfer dynamics (CT) at the interface of graphene/WS van der Waals heterostructure. Pure…
Patterning edge-like defects and tuning defective areas on the basal plane of ultra-large MoS monolayers toward hydrogen evolution reaction
Bianca Rocha Florindo, Leonardo H. Hasimoto, Nicolli de Freitas +11
The catalytic sites of MoS monolayers towards hydrogen evolution are well known to be vacancies and edge-like defects. However, it is still very challenging to control the po…
Splitting of the topologically-protected Dirac cone without breaking time reversal symmetry
L. Seixas, D. West, A. Fazzio +1
Topological insulators (TIs) are a new class of matter characterized by the unique electronic properties of an insulating bulk and metallic boundaries arising from non-trivial bulk…
