By pyrolyzing the material on the substrate, carbon clusters are prevented from forming. Due to the amount of energy required to break the carbon bonds (C-C = 347 kjmol-1, C=C = 614 kjmol-1, C≡C = 839 kjmol-1, C-H = 413 kjmol-1), a high heat is required, and therefore a metal catalyst is required during the process.
The second step is a heat intensive step which assembles the dissociated carbon atoms onto a substrate (in the presence of a catalyst), which forms a single layer structure.
Pyrolyzing - thermal decomposition and thermal assembly as opposed to simple melting
