碳纳米管表面的电子束诱导沉积（EBID）是很好地控制通过不同的电流通过纳米管。控制是由于焦耳加热和碳纳米管的温度估计。沉积速率随温度的升高先增大后减小，在310 K左右达到最大值，在400 K左右接近于零。该方法可用于控制电子束沉积速度的焊接和纳米纤维，并消除无定形碳污染的纳米结构的原位研究。
Electron-beam-induced deposition (EBID) of carbon on the surface of carbon nanotubes was well controlled by passing different electrical currents through the nanotubes. The control is due to Joule heating and the temperature of the carbon nanotubes was estimated. The deposition rate was found to increase and then decrease with the temperature and was maximized at about 310 K and approached zero at about 400 K. The method can be used to control the deposition rate of EBID in nanowelding and nanofabrication and to eliminate amorphous carbon contamination in in situ study of nanostructures.
