Hall effect measurements were conducted on Czochralski grown silicon after implantation of erbium and two step annealing at 700oC and 900oC. At the first step the formation of oxygen-related shallow donors at Ec-20...40 meV as well as erbium-related donor centers at ~Ec-70 meV and ~Ec-120 meV is observed. Along with the same oxygen-related shallow thermal donors and donor centers at ~Ec-70 meV, other donor centers at ~Ec-150 meV are formed following the 900oC anneal, instead of those at ~Ec-120 meV. The new donor states are of keen interest because of their possible involvement in the photoluminescence process. The obtained results for erbium-implanted silicon are compared to some fragmentary DLTS data available in current literature on the donors with ionization energies less than 0.2 eV.
