Abstract

Far-infrared(F-IR) reflection spectra were measured for Bi₂(SeTe)₃ single crystal, and analyzed using dispersion analysis. Dispersion parameters such as damping factor, plasma frequency and ε ∞ were derived by fitting caluculated spectrum to experimental one. It was estimated that and HgBr₂ doping rate dependence of a mobility is mainly contributed by ionized impurity scattering.
