Backscattering of a 2.0-MeV He/sup +/ ion beam and channeling-effect techniques have been used to investigate the lattice location of Te in laser-annealed Te-implanted silicon. After Q-switched ruby-laser irradiation, an attenuation of 85% has been found in the Te signal for beam incidence along the <111> and the <110> axes of a Si crystal implanted with 400-keV Te to a dose of 10/sup 15/ ions/cm/sup 2/. The damaged amorphous layer recrystallizes completely after a 50-MW/cm/sup 2/ pulse of 50-nsec duration for <111>-oriented specimens; a lower power density is sufficient for <100> specimens. The Te profile broadens and shows accumulation at the Si surface for a power density of 60 MW/cm/sup 2/ on a <100> specimen.
