Ultrafast generation of unconventional {001} loops in Si Marqués Cuesta, Luis Alberto Aboy Cebrián, María Santos Tejido, Iván López Martín, Pedro Cristiano, Fuccio La Magna, Antonino Huet, Karim Tabata, Toshiyuki Pelaz Montes, María Lourdes Producción Científica Ultra-fast laser annealing of ion implanted Si has led to thermodynamically unexpected large {001} self-interstitial loops, and the failure of Ostwald ripening models for describing self-interstitial cluster growth. We have carried out molecular dynamics simulations in combination with focused experiments in order to demonstrate that at temperatures close to the melting point, self-interstitial rich Si is driven into dense liquid-like droplets that are highly mobile within the solid crystalline Si matrix. These liquid droplets grow by a coalescence mechanism and eventually transform into {001} loops through a liquid-to-solid phase transition in the nanosecond timescale. 2018-01-16T11:36:07Z 2018-01-16T11:36:07Z 2017 info:eu-repo/semantics/article Physical Review Letters Vol. 119, Iss. 20, 2017 0031-9007 http://uvadoc.uva.es/handle/10324/28070 10.1103/PhysRevLett.119.205503 eng https://journals.aps.org/prl/abstract/10.1103/PhysRevLett.119.205503 info:eu-repo/semantics/openAccess http://creativecommons.org/licenses/by-nc-nd/4.0/ Attribution-NonCommercial-NoDerivatives 4.0 International American Physical Society SI
