Paper Abstract

The fundamental reflectivity spectrum of Hg0.8Cd0.2Te have been investigated. The feature of the spectra is the presence of E1 and E2 peaks with the fundamental absorption region. The lower energy peak can be split into a doublet (E1 and E1 + (Delta) 1). A 3D saddle point is used to fit the E1 and E1 + (Delta) 1 critical point and some simulated calculation is done for E2 at X point. The calculated results are compared with the measured results and prominent features of the dielectric spectra are identified with critical-point transition at the (Lambda) and X points in the Brillouin zone.
