摘要：
In our studies we observed a self-doping effect in Bi 2212 epitaxial thin films, totally covered by a protective golden layer, after the irradiation of these films with heavy ions. The irradiation with heavy ions was made in order to create columnar defects in the samples. We studied Bi 2212 thin films having various oxygen contents before irradiation and we observed for all of them an increase of the oxygen content in the films due to this self-doping effect caused by irradiation.
