“Background Si nanowires (SiNWs) are interesting building blocks of different nanoelectronic devices [1–3], solar cells [4, 5], and sensors [6]. There are different techniques to fabricate vertical SiNWs on a silicon wafer, which include bottom-up methods using catalysts to initiate nanowire growth [7] and top-down methods using either advanced lithographic techniques, combined with anisotropic etching [8], or chemical etching catalyzed by metals (metal-assisted chemical etching (MACE) method) [9, 10]. This last method is a simple low-cost method that permits to obtain vertical Si nanowires on the Si wafer with length that can exceed several tens of micrometers.
