Silicon implanted thermal SiO{sub 2} layers were studied using depth-resolved positron annihilation spectroscopy (PAS) and transmission electron microscopy (TEM). TEM observations show the presence of silicon nanocrystals (Si{sub nc}) in the region between 200 nm and 200 nm. The defect annealing behavior is studied by means of PAS. For 1000{degrees}C annealed samples at a depth for which Si{sub nc} are observed, a distinctive PAS signal is detected and ascribed to the Si{sub nc}/SiO{sub 2} interface
