Abstract

From an inclusion model, the material inhomogeneities of Hg_1-xCd_xTe epilayers were estimated from the anomalous free carrier absorption (FCA) spectra taking into account the composition-in-depth nonuniformity of epilayers. The obtained parameters of the inhomogeneities can also explain the anomalous Hall effect. The investigation offers a nondestructive, simple and reliable tool to characterize the quality of an Hg_1-xCd_xTe epilayer.
