Laser Ordering in Elemental Semiconducting Films
Laser treatment of semiconducting films which are deposited onto fused silica or, else, NaCl crystal before being flotted off and irradiated, is far from being comparable with the annealing process for ion-implanted layers 1 . In the latter, the single crystal substrate induces an epitaxial growth in the implanted layer which overshadows the first step of the Laser-induced ordering. In free-standing semiconducting films or in semiconducting films which are deposited onto fused silica or any amorphous substrate, more insight is probably achieved in this first step and it is the object of this paper to give some overviews on Laser-induced ordering processes in these films.
