Optoelectronic properties of zinc oxide: A first-principles investigation using the Tran-Blaha modified Becke-Johnson potentia
R. M. V. S. Almeida, A. L. da Rosa, J. S. de Almeida
In this work we use density functional theory (DFT) to investigate the influence of semi-local exchange and correlation effects on the electronic and optical properties of zinc oxi…
High-temperature structural phase transition and infrared dielectric features of La2CoMnO6
R. X. Silva, A. Nonato, R. L. Moreira +2
Temperature-dependent FAR-infrared reflectivity spectra of partially ordered magnetodielectric La2CoMnO6 is presented, from room temperature up to 675 K. A clear first-ordered stru…
Intrinsic dielectric properties of magnetodielectric LaCoMnO
R. X. Silva, R. L. Moreira, R. M. Almeida +2
Manganites with double perovskite structure are being attractive because of their interesting magnetoelectric and dielectric responses. Particularly, colossal dielectric constant (…
Group theory for structural analysis and lattice vibrations in phosphorene systems
J. Ribeiro-Soares, R. M. Almeida, L. G. Cançado +2
Group theory analysis for two-dimensional elemental systems related to phosphorene is presented, including (i) graphene, silicene, germanene and stanene, (ii) dependence on the num…
Group Theory analysis of phonons in two-dimensional Transition Metal Dichalcogenides
J. Ribeiro-Soares, R. M. Almeida, E. B. Barros +4
Transition metal dichalcogenides (TMDCs) have emerged as a new two dimensional materials field since the monolayer and few-layer limits show different properties when compared to e…
