摘要：

Results are presented on optical spectra of semiconducting CrSi2 and beta-FeSi2 polycrystalline thin films over the spectral range from 0.02 to 24 eV. For CrSi2, indirect and direct transitions are found at 0.5 and 0.9 eV, respectively. Spectral features at higher energies are attributed to transitions between bonding and antibonding states mediated by energy dependent matrix elements. Simulation of the IR spectra by an oscillator model yields six TO frequencies for both CrSi2 and beta-FeSi2.
