Abstract
The full set of Lorentzian oscillator parameters describing the two-mode phonon behavior in Hg1-x-jCdxTe is reported. A new analysis of reflectivity spectra combined with existing results gives the most accurate available values for the CdTe-like and HgTe-like transverse optical frequency, strength and (for the first time) damping constant vs CdTe fractionx at room, liquid nitrogen and liquid helium temperatures. Polynomial fits vsx for each parameter are provided for use in characterizing Hg1-xCdxTe and the HgTe-CdTe superlattice.
