摘要：
The implantation behaviour of boron in silicon-germanium mixed crystals was studied. The beta-NMR technique was used to measure electric field gradients at boron nuclei in defects. In addition, full-potential DFT calculations were performed to allow the interpretation on the basis of calculated bond lengths and electronic densities. Two defects were identified: a boron-germanium pair on lattice site in a relaxed silicon environment and a complex with interstitial boron. (C) 2001 Elsevier Science B.V. All rights reserved.
