Extended defect structure induced by pulsed laser annealing in Ge implanted Si crystal

The study of extended defects structure induced by the pulsed nanosecond radiation of an excimer laser with different energy density in Si single crystal implanted with Ge ions. Numerical calculations were done to determine the optimal value of the laser energy density causing the epitaxial recrystallization from the melt on a crystal substrate. The RBS were performed to study the near-surface structure of the different areas of the sample. The surface morphology was observed using the interferencepolarizing microscope. Through the application of the section X-ray topography we have observed the crystal lattice deformation caused by laser annealing.
