|Title:||Erbium implantation in strontium titanate|
|Abstract:||We report on the lattice location of Er in SrTiO3 single crystals using the emission channeling technique. The angular distribution of conversion electrons emitted from 167mEr (T1/2 = 2.27 s) was monitored with a position-sensitive detector following the room-temperature 60 keV implantation of the precursor isotope 167Tm (T1/2 = 9.25 d) to a dose of 2 × 1012 at./cm2. The results for the sample annealed in vacuum at 610 °C for 15 min provide direct evidence that Er occupies both Sr and Ti substitutional lattice sites. In addition, thermal recovery of lattice damage was also studied with Rutherford backscattering/channeling for SrTiO3 implanted to doses of 5 × 1014 and 5 × 1015 Er/cm2. We further comment on preliminary photoluminescence results from these samples|
