UNSPECIFIED (2001) Ion-implantation and diffusion behaviour of boron in germanium. In: 21st International Conference on Defects in Semiconductors, GIESSEN, GERMANY, JUL 16-20, 2001. Published in: PHYSICA B-CONDENSED MATTER, 308 pp. 525-528.Full text not available from this repository.
Results are presented of implantation and diffusion study of boron (B) in germanium (Ge). B implantation was carried out in Ge with different energies and to different doses. High-resolution secondary ion mass spectroscopy was used to obtain concentration profiles after furnace annealing. The as-implanted profiles show a long tail possibly due to enhanced diffusion. A limited diffusion has been observed after furnace annealing. Using T-SUPREM, diffusivity value of 1.5(+/-0.3) x 10(-16) cm(2)/s at 850degreesC has been extracted. This value is two orders of magnitude lower than previously reported values. The results question the change in diffusion mechanism of B diffusion in Si-Ge alloys from low Ge levels to high Ge levels. (C) 2001 Elsevier Science B.V. All rights reserved.
