Abstract
For Hg1−xCdxTe, in the range of x≂0.2–0.3, the optical dispersion parameters (single‐oscillator energy E0, dispersion energy Ed, and lattice‐oscillator energy E1) and the fitting parameter of the exponential optical absorption (steepness factor σ) were analyzed using the data by Finkman and co‐workers [J. Appl. Phys. 5 0, 4356 (1979); J. Appl. Phys. 5 6, 2896 (1984)]. For Hg1−xCdxTe the values of E0, Ed, and σ in this composition range are smaller than those for CdTe, and E1 is larger than that for CdTe. The results suggest that the chemical bonding of Hg1−xCdxTe in the range of x≂0.2–0.3 is smaller than that of CdTe.This publication has 19 references indexed in Scilit:
