Far Infrared Properties of Sintered PbTe Doped with Boron

Far infrared spectra of sintered PbTe doped with boron were analyzed. The measured infrared spectra were fitted using a modified plasmon-phonnon interaction model with two additional oscillators (at about 195 cm and 285 cm) representing local B-impurity modes. The obtained results were compared with previously published data for a single crystal PbTe sample… CONTINUE READING
