    • Nanoscale density fluctuations in swift heavy ion irradiated amorphous SiO2 

      Kluth, Patrick; Pakarinen, O. H.; Djurabekova, F.; Giulian, Raquel; Ridgway, M.C.; Byrne, A. P.; Nordlund, K. (2011) [Journal article]
      We report on the observation of nanoscale density fluctuations in 2 μm thick amorphous SiO2 layers irradiated with 185 MeV Au ions. At high fluences, in excess of approximately 5 1012 ions=cm², where the surface is completely ...

    • Role of thermodynamics in the shape transformation of embedded metal nanoparticles induced by swift heavy-ion irradiation 

      Ridgway, M.C.; Giulian, Raquel; Sprouster, David J.; Kluth, Patrick; Araújo, Leandro Langie; Llewellyn, D. J.; Byrne, A. P.; Kremer, Felipe; Fichtner, Paulo Fernando Papaleo; Rizza, G.; Amekura, H.; Toulemonde, M. (2011) [Journal article]

    • Shape transformation of Sn nanocrystals induced by swift heavy-ion irradiation and the necessity of a molten ion track 

      Giulian, Raquel; Kremer, Felipe; Araújo, Leandro Langie; Sprouster, David J.; Kluth, Patrick; Fichtner, Paulo Fernando Papaleo; Byrne, A. P.; Ridgway, M.C. (2010) [Journal article]
      We report on the spherical to rodlike shape transformation of Sn nanocrystals NCs embedded in amorphous SiO2 following irradiation with 185 MeV Au ions. Consistent with previous reports for other metals, transmission ...

    • Tracks and voids in amorphous Ge induced by swift heavy-ion irradiation 

      Ridgway, M.C.; Bierschenk, Thomas; Giulian, Raquel; Afra, Boshra; Rodriguez, M. D.; Araújo, Leandro Langie; Byrne, A. P.; Kirby, Nigel; Pakarinen, O. H.; Djurabekova, F.; Nordlund, K.; Schleberger, M.; Osmani, O.; Medvedev, N.; Rethfeld, B.; Kluth, Patrick (2013) [Journal article]
      Ion tracks formed in amorphous Ge by swift heavy-ion irradiation have been identified with experiment and modeling to yield unambiguous evidence of tracks in an amorphous semiconductor. Their underdense core and overdense ...
