We report a quantitative analysis of the EPR and electron-nuclear double resonance (ENDOR) data associated with the D center in amorphous Si and show that they support the recent suggestion that D centers are not dangling bonds (threefold-coordinated Si atoms) as commonly believed but instead are floating bonds (fivefold-coordinated Si atoms). The localization properties of the D-center wave function are shown to be significantly different from those of the Pb center at the Si-SiO2 interface and from model calculations of dangling bonds. They are, on the other hand, consistent with the predicted properties of floating bonds. We conclude that floating bonds are a stronger candidate for the D center. It is suggested that ENDOR data in enriched29 material may provide a further test of this conclusion. © 1988 The American Physical Society.
