All-Silicon spherical-Mie-resonator photodiode with spectral response in the infrared region

Garín Escrivá, Moisés; Fenollosa Esteve, Roberto; Alcubilla, Ramón; Shi, Lei; Marsal, L. F.; Meseguer Rico, Francisco Javier (Nature Publishing Group, 2014-03)

[EN] Silicon is the material of choice for visible light photodetection and solar cell fabrication. However, due to the intrinsic band gap properties of silicon, most infrared photons are energetically useless. Here, we ...
In situ size sorting in CVD synthesis of Si microspheres

Garín Escrivá, Moisés; Fenollosa Esteve, Roberto; Kowalski, L. (Nature Publishing Group, 2016-11-08)

[EN] Silicon microspheres produced in gas-phase by hot-wall CVD offer unique quality in terms of sphericity, surface smoothness, and size. However, the spheres produced are polydisperse in size, which typically range from ...
Multilayer porous silicon spherical Mie resonator photodiodes with comb-like spectral response in the near infrared region

Fenollosa Esteve, Roberto; Garín, Moisés (Elsevier, 2022-11-01)

[EN] Silicon microsphere photodiodes constitute optoelectronic devices able to provide resonance-enhanced photo -current not only in the visible but also in the near infrared range by virtue of their associated Mie resonances. ...
Porous silicon microcavities: Synthesis, characterization, and application to photonic barcode devices

Ramiro Manzano, Fernando; Fenollosa Esteve, Roberto; Xifre Perez, Elisabet; Garín Escrivá, Moisés; Meseguer Rico, Francisco Javier (SpringerOpen, 2012-09-03)

[EN] We have recently developed a new type of porous silicon we name as porous silicon colloids. They consist of almost perfect spherical silicon nanoparticles with a very smooth surface, able to scatter (and also trap) ...
Spherical silicon photonic microcavities: From amorphous to polycrystalline

Fenollosa Esteve, Roberto; Garín Escrivá, Moisés; Meseguer Rico, Francisco Javier (American Physical Society, 2016-06-16)

[EN] Shaping silicon as a spherical object is not an obvious task, especially when the object size is in the micrometer range. This has the important consequence of transforming bare silicon material in a microcavity, so ...
Thermal Emission of Silicon at Near-Infrared Frequencies Mediated by Mie Resonances

Fenollosa Esteve, Roberto; Ramiro-Manzano, Fernando; GARÍN ESCRIVÁ, MOISÉS; Alcubilla, R. (American Chemical Society, 2019-12-18)

[EN] Planck's law constitutes one of the cornerstones in physics. It explains the well-known spectrum of an ideal blackbody consisting of a smooth curve, whose peak wavelength and intensity depend on the temperature of the ...
