Crystal-oriented wrinkles with origami-type junctions in few-layer hexagonal bo...
Oliveira, Camilla Karla Brites Queiroz Martins de; Gomes, Egleidson Frederik do Amaral; Prado, Mariana C.; Alencar, Thonimar V.; Nascimento, Regiane doUnderstanding layer interplay is the key to utilizing layered heterostructures formed by the stacking of different two-dimensional materials for device applications. Boron nitride has been demonstrated to be an ideal substrate on which to build graphene devices with improved mobilities. Here we present studies on the morphology and optical response of annealed few-layer hexagonal boron nitride flakes deposited ...
Crystal structure of fluorite-related Ln3SbO7 (Ln=La–Dy) ceramics studied by sy...
Siqueira, Kisla Prislen Félix; Borges, Raquel Moreira; Granado, Eduardo; Moreira, Leandro Malard; Paula, Ana Maria de; Moreira, Roberto LuizLn3SbO7 (Ln=La, Pr, Nd, Sm, Eu, Gd, Tb and Dy) ceramics were synthesized by solid-state reaction in optimized conditions of temperature and time to yield single-phase ceramics. The crystal structures of the obtained ceramics were investigated by synchrotron X-ray diffraction, second harmonic generation (SHG) and Raman scattering. All samples exhibited fluorite-type orthorhombic structures with different oxygen ...
Synchrotron X-ray diffraction and Raman spectroscopy of Ln3NbO7 (Ln=La, Pr, Nd,...
Siqueira, Kisla Prislen Félix; Soares, J. C.; Granado, Eduardo; Bittar, Eduardo Matzenbacher; Paula, Ana Maria de; Moreira, Roberto Luiz; Dias, AndersonLn3NbO7 (Ln=La, Pr, Nd, Sm, Eu, Gd, Tb, Dy, Ho, Er, Tm, Yb, and Lu) ceramics were obtained by molten- salt synthesis and their structures were systematically investigated by synchrotron X-ray diffraction (SXRD), second harmonic generation (SHG) and Raman spectroscopy. It was observed that ceramics with the largest ionic radii (La, Pr, Nd) crystallized in to the Pmcn space group, while the ceramics with intermed...
The effect of size dispersion on the optical absorption of a system of semicond...
Vasilevskiy, Mikhail; Akinkina, Evgenia; Paula, Ana Maria de; Anda, EnriqueThe linear optical absorption of an ensemble of semiconductor quantum dots randomly positioned in an insulating matrix is studied theoretically and experimentally for the CdTe/glass system. The calculation of the effective dielectric function of the system, whose imaginary part determines the absorption, is based on a modified Maxwell–Garnett formalism using a diagram technique to calculate the average renormal...
