Figure 4: C diffusion/incorporation mechanism.
From: Atomic scale simulation of carbon nanotube nucleation from hydrocarbon precursors
C diffusion and its incorporation through several steps (a–h) after adsorption and dissociation of C2H2. C and H atoms of the impinging molecule are coloured yellow and red, respectively. C atoms in newly formed hexagon rings at the nanotube edge are coloured black.
