本文介绍了自组生长硅纳米管的制备,并采用5wt%的HF酸对其稳定性进行了研究。 HF酸可去除自组生长硅纳米管的氧化物外层,只剩下晶体硅纳米管。这说明制备的硅纳米管是一种稳定结构,因而对其应用研究开发成为可能。研究表明,硅纳米管的稳定性与其形成生长过程密切相关。自组生长硅纳米管在纳米器件及场发射显示屏等方面具有广泛的应用前景。 This article describes the preparation of self-growing silicon nanotubes and their stability using 5wt% HF acid. HF acid removes the oxide outer layer of self-growing silicon nanotubes, leaving only crystalline silicon nanotubes. This shows that the prepared silicon nanotubes is a stable structure, so its application research and development possible. Studies have shown that the stability of silicon nanotubes is closely related to the formation of the growth process. Self-growth of silicon nanotubes in the nano-devices and field emission display has a wide range of applications.
