Abstract

Diffusion, crystallization and phase separation processes in indium implanted amorphous silicon are examined for low temperature annealing (600°C). Both diffusion and crystallization are shown to be extremely sensitive to the indium concentration. Diffusion coefficients more than 10 orders of magnitude higher than tracer diffusion coefficients in crystalline silicon are measured, and amorphous to crystalline silicon transitions at temperatures as low as 350°C are reported. Phase separation is also observed.
