Vibrational modes activated by structural disorder in FIR transmission of Hg1-x-yCdxMnyTe
Source abstract
Abstract
FIR transmission spectra of HgCdMnTe are investigated over a wide spectral range (from 40 cm-1 up to 400 cm-1) at different temperatures (from 5 K up to 300 K). It is shown that different transverse and longitudinal acoustic, local and resonant modes are activated by disordering and manganese impurities in the range of low values of single-phonon state densities of HgCdTe. FIR spectra seem to be a good probe for characterization of the quality of semimagnetic crystals.
