摘要

Amorphous FeSi2 thin films of stoichiometric composition were deposited on an n-type (1 0 0) Si substrates by laser ablation. In order to investigate the formation and growth processes of the β-FeSi_2 phase, both isothermal annealing and isochronal annealing have been carried out. The results show that the metastable FeSi phase and the β-FeSi_2 phase are dominant at annealing temperatures of T_a≤700 deg C and T_a≥700 deg C, respectively. The growth of the β-FeSi_2 phase is achieved under an annealing condition of T_a≥800 deg C and an annealing time of t_a≥60 min.
