The vacancy profile in Czochralski silicon (111) implanted with 50 keV nitrogen ions has been determined using positron annihilation spectroscopy. The nitrogen distribution has been measured using secondary ion mass spectroscopy. The fitted defect distribution compares well with the results of TRIM calculations.
