Abstract

Damage accumulation and recovery process have been investigated in single crystal SrTiO 3 irradiated with 1.0 MeV Au 2+ using in-situ Rutherford Backscattering Spectrometry (RBS) in Channeling geometry. Samples were irradiated at a temperature of 200 K with ion fluences ranging from 5.0×10 13 - 2.5×10 14 Au 2+/cm 2 (0.22 - 1.10 dpa at damage peak). Subsequent isochronal annealing experiments were performed to study damage recovery processes up to a maximum temperature of 870 K. At an ion fluence between 2.0-2.5×10 14 Au 2+/cm 2 (0.88 - 1.10 dpa), the implanted region, which is just below the surface, becomes amorphous. The recovery processes occur over a broad temperature range, and the damage created by low ion fluences, 5.0×10 13 - 1.0×10 14 Au 2+/cm 2, is almost completely recovered after annealing at 870 K.
