ABSTRACT

Nanostructured porous silicon has shown a range of options — from dendtritic interconnected mesopores to large parallel macropores — the appearance of which is dictated by Si wafer resistivity and dopant identity, electrolyte composition, magnitude and duration of bias, and illumination. This chapter presents a comprehensive review of silicon nanotubes (SiNTs). It explains with preliminary computational studies predicting the properties of single-walled SiNTs (SWSiNTs). The chapter presents an overview of the main fabrication routes of SiNTs currently in use. There are multiple detailed examples of their potentially useful properties in Li battery storage, templates for organometal perovskite formation, magnetically guided drug delivery, surface modification, and other potential uses. The photophysical properties of perovskite/SiNT nanocomposites can be assessed by a combination of photoluminescence (PL) and optical absorption techniques. Functionalization of a Si oxide surface with 3-aminopropyltriethoxysilane (APTES) have possible applications in gene delivery and loading known chemotherapeutic drugs– Cisplatin.
