Abstract
An analysis of X-ray rocking curves and reciprocal space maps recorded for silicon single crystals before and after implantation with a 5×10 14-cm −2 dose of 3 MeV/n nitrogen ions is presented. Silicon single crystals of orientation (100) were obtained by the Czochralski method. X-ray investigations were performed by means of a high-resolution Philips diffractometer using the characteristic Cu Kα 1 radiation, and the integral reflectivities were measured with a double crystal diffractometer using the characteristic Ag Kα 1 radiation. It was stated that irradiation with fast nitrogen ions can create extended defects as well as formation of nano-areas of disordered structure in the silicon crystal. An increase in the surface roughness was also determined from the grazing incidence X-ray reflectivity measurements.
