GaAs微尖上碳纳米管的制备
Fabricating of Carbon Nanotubes on GaAs Microtips
摘要
采用热化学气相沉积的方法在选择性液相外延方法制备的GaAs微尖上生长碳纳米管。利用扫描电子显微镜以及拉曼光谱对生长的碳纳米管进行表征。结果表明: GaAs微尖在高温下重新结晶成条状梯形GaAs阵列, 生长的碳纳米管连接在相邻的GaAs阵列之间, 形态规整, 具有较好的石墨微晶结构。在此基础上, 提出在微尖上生长纳米管的模型, 为实现微纳器件互联提供了一种新方法。
Abstract
Carbon nanotubes (CNTs) fabricated by thermal chemical vapor deposition (T-CVD) on GaAs microtips were investigate. Scanning electron microscope and Raman spectrum were used to characterize the properties of the nanotubes. The results showed that the GaAs tips changed into ladder-like array at high temperature and carbon nanotubes connected the neighbor GaAs with high graphite microcrystal structure. A model for the CNTs grown on GaAs microtips was also proposed. The results presented here make a significant step to the connection for micro or nano devices.
