摘要：
The spin dependent recombination (SDR) technique is used to observe the 29Si hyperfine spectra of radiation-induced Pb centers at the Si/SiO2 interface in a MOSFET. The Pb center is a paramagnetic, trivalent silicon defect that is the dominant radiation-induced interface state. The 29Si hyperfine spectra give detailed atomic scale information about the Pb center. Our SDR results show that the 29Si hyperfine spectra vary with surface potential. This result indicates that differences in the defect's local geometry lead to substantial differences in the defect's energy level. However, the 29Si hyperfine spectra are found to be relatively independent of the ionizing radiation dosage. © 1990 IEEE
