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…
Topological insulating phase arising in transition metal dichalcogenide alloy
F. Crasto de Lima, B. Focassio, R. H. Miwa +1
Transition metal dichalcogenides have been the subject of numerous studies addressing technological applications and fundamental issues. Single-layer PtSe2 is a semiconductor with…
At the verge of topology: vacancy-driven quantum spin Hall in trivial insulators
F. Crasto de Lima, Adalberto Fazzio
Vacancies in materials structure -- lowering its atomic density -- take the system closer to the atomic limit, to which all systems are topologically trivial. Here we show a mechan…
Amorphous BiSe structural, electronic, and topological nature by first-principles
Bruno Focassio, Gabriel R. Schleder, F. Crasto de Lima +2
Crystalline is one of the most explored three-dimensional topological insulator, with a energy gap making it promising for applications. Its amorphous…
Machine learning of microscopic ingredients for graphene oxide/cellulose interaction
Romana Petry, Gustavo Silvestre, Bruno Focassio +3
Understanding the role of microscopic attributes in nanocomposites allows for a controlled and, therefore, acceleration in experimental system designs. In this work, we extracted t…
