Abstract :
Optical phonons in mercury chalcogenides doped with selected transition metal ions (TMI) are investigated by infrared reflectivity and Raman scattering measurements performed at temperatures from 5 to 295 K. The results obtained for Hg1−xFexSe, Hg1−xCoxSe, Hg1−xFexS and Hg1−xCoxS mixed crystals confirm the chemical trends in the dependence of the local mode frequency on the number of 3d electrons of the TMI, reported previously for the wide-gap, zinc-blende II–VI semiconductors.
