Study by ESR and ENDOR of point defects in BeO (in French)
Technical Report
·
OSTI ID:4939056
Paramagnetic point defects created in BeO by irradiation with fast particles (electrons and neutrons) were studied. The two charge states of beryllium vacancies were identified. This defect and its antimorph, the F/sup +/ center, constitute the only intrinsic defects identifiable in metallic oxides. A paramagnetic center obtained by the high-temperature annealing of an irradiated crystal was studied. A simple theoretical calculation was made of the g tensor for which the results confirm the validity of the model proposed (two beryllium vacancies, one of which is situated on the c axis of the crystal and is a close neighbor to an O/sup -/ ion). In addition, an octahedrally positioned interstitial impurity was identified for BeO. (FR)
