Abstract

AbstractIt Will be shown that under suitable conditions ion implanted impurities in Si can precipitate and grow coherently within the single crystal lattice during recrystallization induced by pulsed laser or thermal annealing. Ion channeling and transmission electron microscopy (Tem) were used to characterize such precipitates in Si implanted with Sb and B and thermally annealed, and in Si implanted with Tl and annealed with a pulsed ruby laser.The orientations of these precipitates were determined from TEM and detailed angular scans using ion scattering channeling.The nucleation and precipitation processes will be discussed in terms of differences in the liquid and solid phase regrowth mechanisms.
