Bulk silicon does not show good optical properties because of its indirect band gap. However, when the size of silicon is reduced to nanoscale, the optical properties can be improved. There are many kinds of silicon nanomaterials, such as silicon nanoparticles (SiNPs), silicon nanowires (SiNWs), and silicon nanotubes (SiNTs). SiNPs and SiNWs have already been well investigated, while the research of SiNTs is still very limited, In this study, we focus on the SiNTs. Due to their very high surface area to volume ratio and novel physical properties, SiNTs have good application prospects in many fields. For example, it can be applied to the anode material in lithium ion battery, transistors, and light emitted diodes.
Our aim is to fabricate SiNTs and apply them to the above-mentioned device.
