The temperature dependence of the optical dispersion parameters in Hg0.795Cd0.205Te

摘要

In Hg0.795Cd0.205Te, the optical dispersion parameters (singlehyphen;oscillator energyE0and dispersion energyEd) were analyzed in the temperature range from 100 to 300 K using the data by Finkman and Nemirovsky lsqb;J. Appl. Phys.50, 4356 (1979)rsqb;.E0andEdexhibit large temperature dependence in Hg0.795Cd0.205Te. The signs ofdE0/dTanddEd/dTare positive and absolute values of them are +1.67times;10minus;3eV/K and +17.4times;10minus;3eV/K, respectively.
