Ion track formation and porosity in InSb following 125 MeV and 150 MeV 107 Ag swift heavy-ion irradiation are investigated as a function of ion fluence and irradiation angle. Rutherford backscattering spectrometry in channelling geometry reveals track radii of approximately 5 nm and 8 nm for 125 MeV and 150 MeV ion energies, respectively. The results indicate that the damage fraction saturates at approximately 90% amorphization, suggesting partial recrystallization inhibits complete amorphization. In addition to track formation, a porous structure develops at a fluence of 8 . 8 × 1 0 12 ions/cm 2 , whereas no significant porosity is observed at lower fluences. Notably, the average pore diameter and pore density differ for the different irradiation parameters. • RBS/C reveals track radii of ≈ 5 nm and ≈ 8 nm for 125 MeV and 150 MeV, respectively. • Damage fraction saturates at 90% suggesting partial recrystallization. • For 5° and 30° irradiation angles, the average pore diameter is larger at 125 MeV than at 150 MeV. • For 60° irradiation angle, the average pore diameter is larger at 150 MeV than at 125 MeV.
