Optical properties of PbTe and PbSnTe doped with Cr
(Elsevier, 2009)
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.%, ...
Far infrared study of some rare earth impurities in crystals of Pb 1-xSnx alloys
(Bucharest : National R&D Institute for Optoelectronics, 2009)
Single crystal samples of Pb0.9Sn0.1Te doped with Yb, Sm or Gd were produced using the Bridgman method. Far infrared reflectivity spectra were measured at room temperature for highly polished samples with various impurity ...
Far infrared study of impurity local modes in Pr doped PbTe
(Elsevier, 2009)
Single crystal samples of lead telluride doped with Pr were produced using the Bridgman method. Far infrared spectra of the samples doped with 0.15 at%, 0.25 at% and 0.6 at% Pr are presented. The experimental data were ...
Far infrared study of impurity local modes in palladium-doped PbTe and PbSnTe
(Elsevier, 2009)
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 ...
