Abstract

The stoichiometry-dependent optical properties of bulk samples of TiCx have been determined for four samples in the range 0.64≤x≤0.90. Reflectance and absorptance data taken in the range 0.1-30 eV have been Kramers-Kronig analyzed to obtain the dielectric function and related functions. Interband absorption begins at 0.1 eV or less. The observed interband transitions are interpreted on the basis of existing energy-band calculations. Comparison of optical structure with joint-density-of-states calculations shows that the rigid-band model cannot be applied strictly to explain the x-dependent structure, especially in the 5-10 eV region. The electron-energy-loss functions exhibit two peaks, one near the free-electron plasmon energy and one near 10 eV, both peaks shifting to higher energy as x increases.
