| مستخلص: |
We present a method for selecting fabrication process parameters (temperature, catalyst film thickness, and hydrocarbon concentration) that may be used to grow multiwalled carbon nanotubes (CNTs) with desired outer diameter D and number of walls Nw. This capability enables the control of rigidity, which in turn makes it possible to control a CNT’s lateral vibration behavior and bending stiffness. A growth model was generated and used to link D and Nw to the process parameters. Experimental results showed that the models predicted D and Nw with less than 6% and 7% error, respectively.
