Note:  Silicone wafer  For biological applications, silicone wafer is similar to glass, which makes it a suitable support for the growth and / or nanoparticles being installed in nanowires. For nanoelectronic applications, due to the low background signal and very polished surface, it is an ideal sample bed for small nanoscale particles.

Silicon wafer substrates can be used for sample substrates, micro-fabricated substrates, substrates for nanowires or biological substrates. Useful flat substrate  of silicone wafer particles Bonded with nanowires  and  for biological applications, Si (silicon wafer) has glass-like properties and can be used to mount or grow nanowire particles. It can be easily removed or used as a whole nanowire amplifier wafer. Silicon Nanowire Arrays or SiNWs are vertical arrays of silicon nanowires on a flat crystalline silicon wafer substrate. These nanowires are made by catalytic oxidation and Si dissolution in the presence of metal catalyst nanoparticles - a self-organizing process commonly referred to as the metal-chemical amplified process with the help of  Known as silicone wafers .


The processes of nanowire amplification on   silicon wafers  make Si Nanowire arrays more reproducible and uniform, allowing the properties of nanowires to be adjusted. The nanowire amplification process always involves depositing a metal and bonding it in a solution containing hydrofluoric acid (HF) and an oxidizer. Silicon is produced only where metal nanoparticles touch silicon, so electrochemical reactions with nanoparticle-mediated  As the silicon is transported, the nanoparticles move into the resulting nanoparticles. Because silicon is only locally arched, this process can lead to very high aspect ratio properties in nanowires.

Conclusion : 

Silicone wafer  For biological applications, silicone wafer is similar to glass, making it a suitable support for the growth and / or nanoparticles being installed in nanowires. For nanoelectronics applications, due to the low background signal and highly polished surface, it is an ideal sample bed for small nanoscale particles.
