Se. Daly et al., THE COMPLEXING OF OXYGEN WITH THE GROUP-II IMPURITIES BE, CD AND ZN IN SILICON, Materials science & engineering. B, Solid-state materials for advanced technology, 36(1-3), 1996, pp. 116-119
The results of a photoluminescence study of the Group II elements Be,
Cd and Zn in silicon show that oxygen-rich samples contain defects not
observed in oxygen-lean material. Uniaxial stress and Zeeman measurem
ents show that all the defect spectra are similar and pseudo-donor in
nature. The defects are attributed to complexes of oxygen and the Grou
p II impurity.
