Far infrared study of local impurity modes of Gd doped PbTe
(Elsevier, 2008)
Single crystal samples of lead telluride doped with Gd were grown using the Bridgman method. Far infrared reflectivity spectra in the temperature range from 10 K to 300 K were measured. The experimental diagrams were ...
Far infrared reflectivity spectra of lead-telluride doped with Ytterbium
(Elsevier, 2008)
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 properties of iron doped single crystal PbTe
(Măgurele : National Institute of Research and Development for Optoelectronics, 2008)
Far infrared reflectivity spectra of single crystal PbTe samples doped with 0.2 at% Fe were measured in the temperature range between 10 K and 300 K. These spectra show very sharp and narrow dips below 120 cm-1. The ...
