Electronic transport properties of MoS nanoribbons embedded on butadiene solvent
Armando Pezo, Matheus P. Lima, Marcio Costa +1
Transition metal dichalcogenides (TMDCs) are promising materials for applications in nanoelectronics and correlated fields, where their metallic edge states play a fundamental role…
A tight-binding model for the band dispersion in rhombohedral topological insulators over the whole Brilluoin zone
Carlos Mera Acosta, Matheus P. Lima, Antonio J. R. da Silva +2
We put forward a tight-binding model for rhombohedral topological insulators materials with the space group . The model describes the bulk band structure of…
Topological Phases in Triangular Lattices of Ru Adsorbed on Graphene: ab-initio calculations
C. Mera Acosta, Matheus P. Lima, R. H. Miwa +2
We have performed an ab initio investigation of the electronic properties of the graphene sheet adsorbed by Ru adatoms (Ru/graphene). For a particular set of triangular arrays of R…
Interfaces between buckling phases in Silicene: Ab initio density functional theory calculations
Matheus P. Lima, A. Fazzio, Antonio J. R. da Silva
The buckled structure of silicene leads to the possibility of new kinds of line defects that separate regions with reversed buckled phases. In the present work we show that these n…
Spin Caloritronics in graphene with Mn
Alberto Torres, Matheus P. Lima, A. Fazzio +1
We show that graphene with Mn adatoms trapped at single vacancies feature spin-dependent Seebeck effect, thus enabling the use of this material for spin caloritronics. A gate poten…
Adatoms in graphene as a source of current polarization: Role of the local magnetic moment
Matheus P. Lima, Antônio J. R. da Silva, A. Fazzio
We theoretically investigate spin-resolved currents flowing in large-area graphene, with and without defects, doped with single atoms of noble metals (Cu, Ag and Au) and 3d-transit…
