Abstract

The amorphous latent tracks in ?-Ga2O3 single crystal irradiated with ?5?10;MeV;u(?1) Ta-181 and Kr-86 ions were investigated by transmission electron microscopy (TEM). TEM images showed that the mean diameter of latent tracks increased from 2.2 to 8.8;nm with electronic energy loss (S-e) values increasing from 18.3 to 41.5;keV;nm(?1). Moreover, the inelastic thermal spike model was used to predict the latent track size. The calculation results agreed well with the experimental results and the predicted S-e threshold of latent track formation in ?-Ga2O3 was about 17;keV;nm(?1) for 5?10;MeV;u(?1) heavy ions.
