Characterization of ion track morphology formed by swift heavy ion irradiation in silicon oxynitride films [PDF]

EPJ Web of Conferences, 2015
Amorphous silicon oxynitride (SiOxNy) possess interesting optical and mechanical properties. Here, we present direct evidence for the formation of ion tracks in 1 µm thick silicon oxynitride of different stoichiometries.

Swift heavy ion tracks in SiTiO3 [PDF]

, 2012
Međudjelovanje energetskog teškog iona s materijom može rezultirati dramatičnim promjenama materijala, što čini ozračavanja pojedinačnim ionima jedinstvenim oruđem za modifikacije na nanoskali. Potrebne ekstremne gustoće energije mogu biti postignute koristeći samo brze teške ione (swift heavy ions, SHI) ili ione visokog nabojnog stanja (highly charged

Refractive index engineering through swift heavy ion irradiation of LiNbO₃ crystal towards improved light guidance. [PDF]

Sci Rep, 2017
Swift heavy ion irradiation has been widely used to modify refractive indices of optical materials for waveguide fabrication. In this work, we propose refractive index engineering by swift heavy ion (Ar) irradiation via electronic energy deposition to ...

Comprehensive Understanding of Hillocks and Ion Tracks in Ceramics Irradiated with Swift Heavy Ions

Quantum Beam Science, 2020
Amorphizable ceramics (LiNbO3, ZrSiO4, and Gd3Ga5O12) were irradiated with 200 MeV Au ions at an oblique incidence angle, and the as-irradiated samples were observed by transmission electron microscopy (TEM).

High-Energy Heavy Ion Tracks in Nanocrystalline Silicon Nitride

Crystals, 2022
At present, silicon nitride is the only nitride ceramic in which latent ion tracks resulting from swift heavy ion irradiation have been observed. Data related to the effects of SHIs on the nanocrystalline form of Si3N4 are sparse.
