Silicon nanowires have the following characteristics:
Si nanowires have unique optical properties such as fluorescence and ultraviolet; electrical properties such as field emission and electron transport; thermal conductivity, high surface activity, and quantum confinement effects.

1. Applications of nano silicon wire sensors
Drawing on the current research foundation of silicon-based materials and the existing research results of nano-sensor preparation, silicon nano wires are used to synthesize nano-sensors with high sensitivity, real-time monitoring and self-healing ability.

2. Silicon Nanowire Transistors
Using nano Si wires as the main structural unit, a variety of transistors such as silicon nanowire FETs, single-electron transistors (SETs) and field-effect phototransistors have been fabricated.

3. Photodetector
Studies have shown that silicon nanowires have the characteristics of high direct polarization sensitivity, high spatial resolution, and easy compatibility with other optoelectronic components fabricated by "bottom-up" methods, so they can be used in future integrated nano optoelectronic systems.

4. Si nano wire lithium-ion anode material battery
Silicon is the anode material with the highest theoretical lithium storage capacity found so far, and its specific capacity is much higher than that of graphite materials, but its actual lithium intercalation is closely related to the size of the silicon on the electrode, the electrode formulation, and the charge-discharge rate. The new lithium-ion battery made from SiNWs can store up to 10 times more power than conventional rechargeable batteries. The key to its technology is to improve the storage capacity of the battery anode.
