/sup 29/Si hyperfine structure of unpaired spins at the Si/SiO/sub 2/ interface
Journal Article
·
· Appl. Phys. Lett.; (United States)
The hyperfine spectrum associated with unpaired electrons at the (111) Si/SiO/sub 2/ interface (P/sub b/ centers) is reported for the first time. Electron paramagnetic resonance measurements indicate that the hyperfine interaction SxA-barxI arises from the /sup 29/Si isotope and is characterized by A/sub parallel/ = 146.( +- 5.) x 10/sup -4/ cm/sup -1/ and A/sub perpendicular/ = 85.( +- 8.) x 10/sup -4/ cm/sup -1/. An analysis of this hyperfine interaction firmly establishes many of the details in the structure of this interface defect.
