High resolution spectra of defects in CdTe obtained in far-infrared region using synchrotron radiation

The present work analyses the lattice deformations induced in the crystals with tetrahedral coordination by the presence of impurity hydrogen and oxygen atoms. Such deformations can be monitored by analyzing of far-infrared (FIR) vibration spectra. FIR experiments carried out on hydrogenated CdTe crystals that successfully revealed the presence and localization of hydrogen atoms within the lattice.
