“…It can be also observed that the nanowires tips sticked together, and the bundles are formed. This is due to van der Waals forces as was suggested previously [29].The diameter of a single nanowire is in the range of 20-100 nm. The crosssection image, displayed in Fig.…”

It has been found that the silicon nanowires modified with noble metals can be used to fabricate an effective H 2 gas sensor in the present study. The preparation and surface modification of silicon nanowires (SiNWs) were carried out by chemical methods. The morphology of the silicon nanowires unmodified and modified with nanoparticles of platinum, palladium, silver and gold was investigated using scanning electron microscopy (SEM). The chemical composition of the silicon nanowire layers was studied by secondary ion mass spectroscopy (SIMS) and energy dispersive X-ray analysis (EDX). The structures of type metal/SiNWs/p-Si/Al were fabricated. The electrical characterization (I-V) was performed in primary vacuum and H 2 at different concentrations. It was found that the metal type used to modify the SiNWs strongly influenced the I-V characteristics. The response of these structures toward H 2 gas was studied as a function of the metal type. Finally, the sensing characteristics and performance of the sensors were investigated.

“…In the present study, we cultured postnatal day 4 (PN4) mouse retinal cells on Si NW substrates produced using metal assisted chemical etching (MACE), which produces high aspect ratio pores in Si. 25,26 We assessed the cell distribution, morphology, as well as the expression of retinal cell functional markers using immunocytochemistry aer 3 and 18 days in vitro (DIV) on Si NW and used at silicon substrates as controls.…”
