Far infrared reflectivity spectra of lead-telluride doped with Ytterbium
Single crystal samples of lead-telluride doped with Ytterbium were made using the Bridgman method. Far infrared reflectivity spectra in the temperature range from 10 to 300 K were measured. Analysis of the experimental ...
Far infrared study of impurity local modes in palladium-doped PbTe and PbSnTe
PbTe and Pb0.85Sn0.15Te single crystals, doped with Pd, were grown using the Bridgman method. Far infrared spectra were measured in the temperature range between 10 K and 300 K. The experimental spectra were numerically ...
Optical properties of PbTe and PbSnTe doped with Cr
Single crystal samples of PbTe and PbSnTe doped with Cr were made using the Bridgman technique. Far infrared diagrams of PbTe samples doped with 0.4 at.%, 0.8 at.% and 1 at.% Cr and also of Pb0.9Sn0.1Te doped with 0.4 at.%, ...
