Notes:
12B probe nuclei are implanted in amorphous Si and monitored by β-radiation-detected nuclear magnetic resonance (β-NMR). Independently of growth conditions and impurity content, we find the same frequency distribution in a variety of samples. This is interpreted as an intrinsic signature of the amorphous environment while preferential B–H pairing is not observed. Comparing our data with earlier 11B-NMR work, we find the local B configuration to be completely controlled by the incorporation process. In our low-dose implantation experiment, all B is fourfold coordinated and electrically active. This is in contrast to gas-phase doping or high-dose implantation where the threefold coordination prevails. © 2001 American Institute of Physics.
