Graphene and its derivatives have become the most explored materials since Novoselov and Geim (Nobel Prize winners for Physics in 2010) achieved its isolation in 2004. The exceptional properties of graphene have attracted ... -
Optimization in nanocoated D-shaped optical fiber sensors
Del Villar, Ignacio ; Zubiate Orzanco, Pablo ; Ruiz Zamarreño, Carlos ; Arregui San Martín, Francisco Javier ; Matías Maestro, Ignacio (Optical Society of America, 2017)
Artículo / Artikulua
Nanocoated D-shaped optical fibers have been proven as effective sensors. Here, we show that the full width at half minimum (FWHM) of lossy mode resonance can be reduced by optimizing the nanocoating width, thickness and ... -

Ultrahigh-sensitivity sensors based on thin-film coated long period gratings with reduced diameter, in transition mode and near the dispersion turning point
Del Villar, Ignacio (Optical Society of America, 2015)
Artículo / Artikulua
The mode transition and the dispersion turning point have been explored for optimization of thin-film coated long period fiber gratings during the last years. In this work and additional parameter, the cladding diameter, ... -
Vanadium trapped by oblique nano-sheets to preserve the anisotropy in Co-V thin films at high temperature
Favieres Ruiz, Cristina ; Vergara Platero, José ; Magén, César; Ibarra, Manuel Ricardo; Madurga Pérez, Vicente (Elsevier, 2022)
Artículo / Artikulua
In this study, oriented nano-sheets generated during the growth of cobalt-rich Co–V and Co–Zn thin films induced a large anisotropy in the magnetic and transport properties. The regular nano-sheets were tilted 52–54 deg. ... -
