Resonant helical multi-edge transport in Sierpiński carpets
M. A. Toloza Sandoval, A. L. Araújo, F. Crasto de Lima +1
In recent years, synthesis and experimental research of fractalized materials has evolved in a paradigmatic crossover with topological phases of matter. We present here a theoretic…
Design of spin-orbital-textures in ferromagnetic/topological insulator interfaces
A. L. Araújo, F. Crasto de Lima, C. H. Lewenkopf +1
Spin-orbital textures in topological insulators due to the spin locking with the electron momentum, play an important role in spintronic phenomena that arise from the interplay bet…
Electronic and spin transport in Bismuthene with magnetic impurities
Armando Pezo, Felipe Crasto de Lima, Adalberto Fazzio
Topological insulators have remained as candidates for future electronic devices since their first experimental realization in the past decade. The existence of topologically prote…
Substrate suppression of oxidation process in pnictogen monolayers
R. L. H. Freire, F. Crasto de Lima, A. Fazzio
2D materials present an interesting platform for device designs. However, oxidation can drastically change the system's properties, which need to be accounted for. Through {\it ab…
Bridging Borophene and Metal Surfaces: Structural, Electronic, and Electron Transport Properties
Wanderlã L. Scopel, F. Crasto de Lima, Pedro H. Souza +2
Currently, solid interfaces composed of two-dimensional materials (2D) in contact with metal surfaces (m-surf) have been the subject of intense research, where the borophene bilaye…
Uncovering the Structural Evolution Arsenene on SiC Substrate
A. K. Okazaki, R. Furlan de Oliveira, R. L. H. Freire +2
Two-dimensional arsenic allotropes have been grown on metallic surfaces, while topological properties have been theoretically described on strained structures. Here we experimental…
Nanoscale Structural and Electronic Properties of Cellulose/Graphene Interfaces
Gustavo H. Silvestre, Felipe Crasto de Lima, Juliana S. Bernardes +2
The development of electronic devices based on the functionalization of (nano)cellulose platforms relies upon an atomistic understanding of the structural, and electronic propertie…
Vacancy localization effects on MX2 transition metal dichalcogenides: a systematic ab-initio study
Rafael L. H. Freire, Felipe Crasto de Lima, Adalberto Fazzio
Two-dimensional transition metal dichalcogenides (MX) vacancy formation energetics is extensively investigated. Within an ab-initio approach we study the MX systems, with M…
The role of functional thiolated molecules on the enhanced electronic transport of interconnected MoS nanostructures
Rafael L. H. Freire, Felipe Crasto de Lima, Rafael Furlan de Oliveira +2
Molecular linkers have emerged as an effective strategy to improve electronic transport properties on solution-processed layered materials via defect functionalization. However, a…
Electronic properties of the Weyl semimetals CoMnX (X=Si, Ge, Sn)
Abhishek Sharan, Felipe Crasto de Lima, Shoaib Khalid +2
Using first-principles electronic structure calculations, we show that ferromagnetic Heusler compounds CoMnX (X= Si, Ge, Sn) present non-trivial topological characteristics and…
Identifying the fingerprints of topological states by tuning magnetoresistance in a semimetal: the case of topological half-Heusler Pt1-xAuxLuSb
Shouvik Chatterjee, Felipe Crasto de Lima, John A. Logan +18
Topological materials often exhibit remarkably linear, non-saturating magnetoresistance (LMR), which is both of scientific and technological importance. However, the role of topolo…
Tuning the topological states in metal-organic bilayers
F. Crasto de Lima, Gerson J. Ferreira, R. H. Miwa
We have investigated the energetic stability and the electronic properties of metal-organic topological insulators bilayers (BLs), -BL, with M=Ni and Pt, using first-p…
