Optical Absorption in Doped CdxHg1-xTe.

Abstract

The theory of optical absorption is heavily doped (degenerate) CMT is formulated to make use of the most recently measured band parameters. The absorption theory is compared with Anderson's approximation of Kane's k.p. theory. The differenced are found to be small near threshold, due to a somewhat fortuitous cancellation of errors. The dispersion of the refractive index near the band gap is calculated. This has only a small effect on the calculated absorption, but could be of importance in modelling interference fringes on thin detectors.
