FREE CARRIER ABSORPTION SPECTRA FOR Hg 1-x Cd x Te EPILAYERS

The free carrier absorption spectra for Hg 1-x Cd x Te epilayers are derived by considering the composition-in-depth nonuniformity and Te precipitates in the epilayers. The results show that the absorption behaviour of epilayers exhibits many differences with that of the bulk materials. The Te precipitates may exist when the calculated transmission is much higher than the experimental data.
