The dewetting of a low melting point metal thin film deposited on silicon substrates was studied. The experimental results suggest that the change in the growth temperature affects the nanostructures that form. Based on the experimental results, the temperature which yielded the smallest features for the growth of nanotubes is determined. The mechanism by which these nano-templates become an efficient seeds for the growth of the carbon nanotubes is discussed. The partial bismuth filling inside the CNTs was optimized. Based on the results, a schematic growth model for better understanding of the process parameters has also been proposed.
研究了沉积在硅衬底上的低熔点金属薄膜的去湿现象。实验结果表明，生长温度的变化会影响所形成的纳米结构。基于实验结果，确定了产生纳米管生长最小特征的温度。讨论了这些纳米模板成为碳纳米管生长有效种子的机制。优化了碳纳米管内部的部分铋填充。基于这些结果，还提出了一个示意性的生长模型，以便更好地理解工艺参数。
