Transient Structural Relaxation and Melting Temperature of Amorphous Silicon


The structure of ion-implanted a-Si has been studied using Raman spectroscopy. It is shown that the average bond-angle distortion and the strain energy stored in the random network vary drastically upon annealing. Relaxation is enhanced in the case of heating by laser irradiation. The results imply that the apparent melting temperature of a-Si may vary from one experiment to another, depending on the heating rate and -method.

    The expression for ΔΘb vs. Γ/2 (formula 1) and that for UΘ vs. ΔΘb (formula 2) used in this paper differ from those given by Tsu et al. [10]. These differences are due to an uncertainty in the relation between the Raman spectrum and the degree of disorder in a-Si and to different estimates of the elastic constant β. We feel that the expressions used here yield more realistic values of the strain energy than the expressions in [10].
