SDR-EPR spectra for natSi and 28Si samples recorded at 16 K with B||. The samples were measured after native oxide formation at room temperature in air for 17 days.
Angular dependences of the g-factors of SDR-EPR spectra detected in 28Si sample rotated around crystal axis. The experimental points (•) are compared with calculation based on previously reported spin Hamiltonian parameters for phosphorus (dotted line)27 and Pb (broken curves).12 The dashed line and the solid curves are calculated g-factor components for I (g = 1.9996(2)) and Pm, respectively.
Time dependences of the SDR-EPR signal intensities detected in the sample kept at room temperature in air after termination of the sample surface by hydrogens. The measurement was performed at T = 16 K with B||. The signal intensities of Pm (•) and Pb (▴) were normalized by the maximum intensities at 8 days and 10 days for Pm and Pb, respectively.
