Unidirectional current flow (diode-like behavior) is observed in Al/Nanostructured Porous Silicon/Al structures (Al/SP/Al) after applying a forming electric field (E) for a long time. We found that rectifying characteristics ...

We report measurements of secondary electron emission (SEE) induced by electron and ion bombardment on porous silicon (PS). We found that electron induced emission is strongly reduced by ion bombardment, and that this ...

Porous silicon is characterized by a large specific area and a large chemical reactivity. These characteristics, although attractive for sensing applications, led to an unstable behaviour. Different oxidation methods have ...

This paper presents an optical method for real-time monitoring of protein adsorption using porous silicon self-supported microcavities as a label-free detection platform. The study combines an experimental approach with a ...

Elastic properties of freestanding porous silicon layers fabricated by electrochemical anodization were studied by Raman scattering. Different anodization currents provided different degrees of porosity in the nanometer ...

In this work, we study the optical response of structures involving porous silicon and porous alumina in a multi-layered hybrid structure. We performed a rational design of the optimal sequence necessary to produce a high ...
