Notes:
Ion-beam-induced epitaxial crystallization of amorphous Si implanted with Fe to 18 at. % peak concentration was studied. The structure of the specimen was characterized using transmission electron microscopy and Rutherford backscattering spectrometry. Both cubic FeSi2 and α-FeSi2 were formed in epitaxy with the Si matrix with two types of orientations (fully aligned and twinned). The twins of α-FeSi2 and those of cubic FeSi2 were found to have exactly the same type of epitaxial relationship as for the aligned ones. The thermodynamically stable β-FeSi2 is not formed, demonstrating that ion-beam-induced crystallization can lead to preferential phase formation as well as to epitaxy.
