摘要： The point defects of Pb and E′ in radiation hard and soft Si-SiO2 samples were examined using electron spin resonance (ESR). The experimental results showed that these defects were correlated with the ways of oxidation process, the dosage of 60Co radiation and the radiation bias field. Besides, the ΔH (peak of peak) of Pb and E′ indicated that Pb is the defect with slow electron spin relaxation time while E′ is the defect with fast electron spin relaxation time. Finally, the experimental results are explained qualitatively.

Besides, the $\Delta$H (peak of peak) of Pb and E′ indicated that Pb is the defect with slow electron spin relaxation time while E′ is the defect with fast electron spin relaxation time. Finally, the experimental results are explained qualitatively.
