概要（目的・用途・実施内容）/ Abstract (Aim, Use Applications and Contents)

We synthesized one-dimensional van der Waals heterostructures (heteronanotubes) and use advanced TEM/STEM to characterize their structures.

実験 / Experimental

one-dimensional van der Waals heterostructures are synthesized by chemical vapor depsition using network Single-walled carbon nanotubes as template. The obtained heteronanotube films are then transfer onto a Mo or Si grid for TEM characterization.

結果と考察 / Results and Discussion

This time we checked one special starting material, which is chirality specific single-walled carbon nanotube obtained from a seperation technique. The TEM images show that tubes are almost individual, and not forming bundles. The reason behind this is these nanotubes are wrapped by some polymers, which can be clearly visuallized by the attached TEM images. Furthermore, the obtained tubes have very similar diameter, suggesting that they may be pure (6,5) carbon nanotubes. Some defects are observed in these images, which is also consistent with other characterizations.
