On the vibrational properties of transition metal doped ZnO: surface, defect, and bandgap engineering
Viviane M. A. Lage, Carlos Rodríguez-Fernández, Felipe S. Vieira +5
We present a comprehensive study on the structure and optical properties of Mn-and Co-doped ZnO samples prepared via solid-state reaction method with different dopant concentration…
Monolayer-to-mesoscale modulation of the optical properties in 2D CrI3 mapped by hyperspectral microscopy
Marta Galbiati, Fernando Ramiro-Manzano, José Joaquín Pérez Grau +8
Magnetic 2D materials hold promise to change the miniaturization paradigm of unidirectional photonic components. However, the integration of these materials in devices hinges on th…
Raman Signal Reveals the Rhombohedral Crystallographic Structure in Ultra-thin Layers of Bismuth Thermally Evaporated on Amorphous Substrate
Carlos Rodríguez-Fernández, Kim Akius, Mauricio Morais de Lima +3
Under the challenge of growing a single bilayer of Bi oriented in the (111) crystallographic direction over amorphous substrates, we have studied different thicknesses of Bi therma…
Defect Induced Room Temperature Ferromagnetism in High Quality Co-doped ZnO Bulk Samples
M. P. F. de Godoy, X. Gratens, V. A. Chitta +6
The nature of the often reported room temperature ferromagnetism in transition metal doped oxides is still a matter of huge debate. Herein we report on room temperature ferromagnet…
Thermally Tunable Surface Acoustic Wave Cavities
André Luiz Oliveira Bilobran, Alberto García-Cristóbal, Paulo Ventura dos Santos +2
We experimentally demonstrate the dynamical tuning of the acoustic field in a surface acoustic wave (SAW) cavity defined by a periodic arrangement of metal stripes on LiNbO3 substr…
Nanowires: A route to efficient thermoelectric devices
F. Dominguez-Adame, M . Martin-Gonzalez, D. Sanchez +1
Miniaturization of electronic devices aims at manufacturing ever smaller products, from mesoscopic to nanoscopic sizes. This trend is challenging because the increased levels of di…
