These videos show the thermal spike arising from a 100 eV C atom impinging on a growing tetrahedral amorphous carbon film, as simulated with a GAP potential [1,2,3] following the deposition protocol and methodology outlined by Caro et al. [4,5]. The molecular dynamics simulations (MD) were carried out with QUIP's GAP implementation [6] using LAMMPS [7,8] as MD engine. The atomic visualization was carried out with VMD [9,10]. The final videos were composed using, in addition, the following software: gnuplot [11], Inkscape [12] and FFmpeg [13]. References A.P. Bartók, M.C. Payne, R. Kondor, and G. Csányi. Phys. Rev.
