Abstract: Silicon nanowire is a new type of low-dimensional nanomaterials,which are widely used in solar cells,lithium-ion batteries,field effect transistors and biosensors.The mechanism of gas-liquid-solid growth,solid-liquid-solid growth and oxide-assisted growth were detailedly introduced.The advantages and disadvantages of various growth mechanisms were summarized.Finally,the related applications of silicon nanowire were also introduced and then looking forward to its development tendency.

Key words: silicon nanowire;growth mechanism;preparation
