We use two different methods to fabricate nanostructured silicon on the surface of C-Si: femtosecond laser etching (FLE) and deep reactive ion etching (DRIE) combined with plasma immersion ion implantation (PIII). Nanocone silicon arrays of dense and random distribution are obtained by FLE. Meanwhile, cylindroid silicon nanostructures of excellent regularity and uniform coverage are achieved by DRIE. These nanostructured silicon materials show a remarkable enhancement on absorptance at near-infrared wavelength. Moreover, the minority carriers lifetime measurement is also carried out to evaluate defect states caused by two etching processes and their influence on semiconductor physical effects. A Si-PIN photoelectronic detector with nanostructured silicon at the back surface exhibits high near-infrared responsivity. These novel results may have a potential application in near-infrared photoelectronic devices.

Highly Sensitive Detection

In this paper, we report on the realization of a highly sensitive and low cost 3D surface-enhanced Raman scattering (SERS) platform. The structural features of the Ag dendrite network that characterize the SERS material were exploited, attesting a remarked self-similarity and scale invariance over a broad range of length scales that are typical of fractal systems. Additional structural and optical investigations confirmed the purity of the metal network, which was characterized by low oxygen contamination and by broad optical resonances introduced by the fractal behavior. The SERS performances of the 3D fractal Ag dendrites were tested for the detection of lysozyme as probe molecule, attesting an enhancement factor of ~2.4 × 106. Experimental results assessed the dendrite material as a suitable SERS detection platform for biomolecules investigations in hydration conditions.
