A TDPAC study of the lattice location of implanted indium in silicon

Abstract
The annealing behaviour of indium implanted silicon (doses 1011−1013 atoms/cm2) was studied by time differential perturbed angular correlation spectroscopy. Besides the substitutional site two types of defect configurations were observed. In the as-implanted condition the substitutional In fraction remains below 20% even at the lowest dose. This result is in accordance with the prediction of the track amorphization model.
