Reflectivity and electronic structure of Pd silicides

Abstract
The reflectivities of Pd and Pd silicides have been measured from 0.5 to 6 eV and compared with the existing density of states and band calculations as well as with the optical spectra of other silicides. The rather complex spectra resulting from the superposition of the free carrier response and inter-band transitions are discussed and some indications concerning their interpretation are drawn.
