All-silicon spherical-Mie-resonator photodiode with spectral response in the infrared region
(2014-03-10)
Article
Accés obertSilicon 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 show ... -
Light harvesting by a spherical silicon microcavity
(American Institute of Physics (AIP), 2016)
Article
Accés obertSilicon colloids are presented as efficient absorbers in the VIS-NIR region. The theory of resonant absorption by Mie modes in a single high-index sphere is reviewed and engineering rules established. The presented model ... -
Silicon microcavity-based photovoltaic cells for IR harvesting
(2014-05-22)
Article
Accés obertPhotovoltaic cells on silicon spherical microcavities trap IR light, increasing the probability of photon absorption and enhancing the efficiency of solar energy devices. -
Silicon nanocavities: Optical properties and applications
(2014)
Text en actes de congrés
Accés obertSilicon is the key enabling material for advanced technologies in electronics, and photonics. Recently, we have developed silicon nanocavities (SNs) [1,2] with particle size between 300 nm and 3000 nm. Silicon has an ... -
Spherical silicon photonic microcavities : From amorphous to polycrystalline
(2016-06-16)
Article
Accés obertShaping 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 it is ...
