Abstract

We report the nuclear magnetic resonance (NMR) spectra of phosphorus-doped single-crystal silicon, enriched to 97% 29Si, which display double as well as single peaks as the sample is rotated with respect to the static magnetic field. It is shown that the shape and the width of the NMR lines are predominantly due to nuclear dipolar interactions. We provide a theoretical model to determine the strength of the weaker scalar coupling between neighboring 29Si nuclei. For naturally abundant single-crystal silicon (4.7% 29Si), the anisotropic dipolar interaction is visible as well in the NMR spectra. We have observed small side peaks for particular orientations of the crystal axes and we show that the intensity of the side peaks contains information on the distribution of 29Si atoms in the 28Si matrix.
