    Description:
    SWCNT, crystallinity can be defined on two different levels:
    1_On atomic level, which is the graphitic lattice structure found in the starting material based on Raman spectroscopy.
    2_On 3D level, there is no three-dimensional, hierarchically layered structure in as-growth SWCNT based on TEM images.
