Molecular dynamics simulations of the structure of latent tracks in quartz and amorphous SiO 2

Pakarinen, Olli; Djurabekova, Flyura; Nordlund, Kai; Kluth, Patrick; Ridgway, Mark C


Swift heavy ion irradiation (SHII) can leave a latent ion track around the ion path. Tracks in amorphous silicon dioxide (a-SiO2) and quartz are interesting due to applications in nanofabrication, for example. In recent experiments, a previously unresolved fine structure in latent ion tracks in a-SiO2 was found comprising a lower density core and a higher density shell. We model the formation of latent ion tracks in crystalline quartz and amorphous SiO2 using classical molecular dynamics (MD)...[Show more]
