Characteristics of 2 MeV N+-implanted damage in GaSb samples with doses from 1 × 1013 cm−2 to 1 × 1015 cm−2 were studied by use of spectroscopic ellipsometry, Rutherford backscattering spectrometry in combination with the channeling technique, and scanning electron microscopy methods. When doses are greater than 3 × 1014 cm−2, the implanted layer becomes amorphous. But no swelling was observed on the implanted sample surfaces, as predicted by R. Callec. By rapid thermal annealing at 600°C for 25 s, a good recovery of the implanted layers has been achieved. |
