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…
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…
Exploring Topological Transport in PtHgSe Nanoribbons: Insights for Spintronic Device Integration
Rafael L. H. Freire, F. Crasto de Lima, Roberto H. Miwa +1
The discovery of the quantum spin Hall effect led to the exploration of the electronic transport for spintronic devices. Here, we theoretically investigated the electronic conducta…
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…
Orbital pseudospin-momentum locking in two-dimensional chiral borophene
Felipe Crasto de Lima, Gerson J. Ferreira, Roberto H. Miwa
Recently, orbital-textures have been found in Rashba and topological insulator (TI) surface states as a result of the spin-orbit coupling (SOC). Here, we predict a orbita…
