Silicon nanowires exhibit a distinct and useful self-limiting oxidation behaviour whereby oxidation effectively ceases due to diffusion limitations, which can be modeled. [1] This phenomenon allows accurate control of dimensions and aspect ratios in SiNWs and has been used to obtain high aspect ratio SiNWs with diameters below 5 nm. [ 19 ]
Silicon nanowires have a theoretical capacity of roughly 4,200 mAh g −1, larger than that of other forms of silicon and much larger than that of graphite (372 mAh g −1). [3] Like graphite anodes, silicon anodes form passivation layers (solid-electrolyte interphases) on their surfaces during the first charge cycle. Coating silicon nanowires ...
In copper, for example, the mean free path is 40 nm. Copper nanowires less than 40 nm wide will shorten the mean free path to the wire width. Silver nanowires have very different electrical and thermal conductivity from bulk silver. [34] Nanowires also show other peculiar electrical properties due to their size.

Some of these candidates include: hybrid molecular/semiconductor electronics, one-dimensional nanotubes/nanowires (e.g. silicon nanowires or carbon nanotubes) or advanced molecular electronics. Nanoelectronic devices have critical dimensions with a size range between 1 nm and 100 nm. [1]
However, the large volume change of the nanowires can still pose a fading problem. Other studies examined the potential of silicon nanoparticles. Anodes that use silicon nanoparticles may overcome the price and scale barriers of nanowire batteries, while offering more mechanical stability over cycling compared to other silicon electrodes. [32]

The morphology of the nanowires allowed the electrons to have a direct pathway to the photoanode. This form of solar cell exhibits 50–60% internal quantum efficiencies. [101] Nanowires with quantum dot coatings on silicon nanowires (SiNW) and carbon quantum dots.
