Influence of doping on the liquid-amorphous transition induced by picosecond laser irradiation of Si

Abstract
The effect of Bi doping on the quench of amorphous Si directly from the melt during 30-ps, 0.53-μm laser irradiation has been studied. The amorphous thickness (45 nm) in Bi implanted samples was observed to increase 50% over the corresponding undoped samples (25 nm). No change in the Bi profile was detected upon amorphization.
