EXPERIMENTAL AND THEORETICAL-STUDY OF THE OPTICAL-PROPERTIES OF CRYSTALLINE AND AMORPHOUS TISI2 FILMS

Optical properties of amorphous and polycrystalline TiSi2 films have b een studied experimentally in a wide spectral range (0.5-5.0 eV). The structures in the optical conductivity spectrum of polycrystalline TiS i2 sample are explained on the basis of comparison of the experimental data and the calculated data. Theoretical spectra were obtained withi n the local-density approximation using the semirelativistic linear-mu ffin-tin-orbital method (LMTO). It is shown that the transition of cry stalline TiSi2 to the amorphous state leads to significant changes in the optical properties. (C) 1997 American Institute of Physics.
