AB  - PbTe single crystals doped with monovalent Au or Cu were grown using the Bridgman method. Far infrared reflectivity spectra were measured at room temperature for all samples and plasma minima were registered. These experimental spectra were numerically analyzed and optical parameters were calculated. All the samples of PbTe doped with Au or Cu were of the "n" type. The properties of these compositions were analyzed and compared with PbTe containing other dopants. The samples of PbTe doped with only 3.3 at% Au were the best among the PbTe + Au samples having the lowest plasma frequency and the highest mobility of free carriers-electrons, while PbTe doped with Cu was the opposite. Samples with the lowest Cu concentration of 0.23 at% Cu had the best properties. Thermal diffusivity and electronic transport properties of the same PbTe doped samples were also investigated using a photoacoustic (PA) method with the transmission detection configuration. The results obtained with the far infrared and photoacoustic characterization of PbTe doped samples were compared and discussed. Both methods confirmed that when PbTe was doped with 3.3 at% Au, thermoelectric and electrical properties of this doped semiconductor were both significantly improved, so Au as a dopant in PbTe could be used as a new high quality thermoelectric material. © 2015 Pantelija M.

AB  - In this work, n-type and p-type PbTe doped with Br and Na, respectively, were thoroughly examined to determine the effect of the dopant on microstructure. Macro and micro homogeneity of the samples were studied by means of micro-Fourier-transform infrared (micro-FTIR) spectroscopy, micro-Seebeck measurements, and scanning electron microscopy with energy-dispersive x-ray analysis (SEM/EDX). SEM/EDX observations showed the samples were not single-phase materials—second phases were created by inclusions that disturbed the coherence of the matrix and, subsequently, drastically affected the Seebeck coefficient. In a micro-scale study, local variations of sodium content were detected in Na-doped samples; in Br-doped samples a second, PbBr2, phase was observed in the PbTe matrix. A direct effect of matrix dopant on Seebeck coefficient and plasmon frequency for the Br-doped and Na-doped samples was observed by use of the three complementary techniques.

AB  - PbTe single crystal samples doped with Mn and Yb were grown using the Bridgman method. Far infrared reflectivity spectra were measured at room temperature for samples with different impurity concentrations (total impurity concentration Mn+Yb varied between 0.59 and 2.52 at%, while the impurity Mn/Yb ratio varied between 0 and 3.48). All samples were of the "p" type. Plasma minimum was registered for all samples and varied between 114 and 198 cm-1 depending on the total impurity concentration and ratio. Samples with lower plasma minimum had a higher free hole mobility, with the highest value of 7000 cm2/Vs determined for a sample with the highest Mn/Yb ratio of 3.48 (1.67 at.% Mn and 0.48 at.% Yb).

AB  - Far infrared reflectivity spectra of sintered Pb 0.9Sn 0.1Te doped with 0.2 and 2 at.% Pd are measured. The experimental results are analyzed using a fitting procedure based on a modified plasmon-phonon interaction model. The values of calculated parameters are compared with literature data for PbTe and PbSnTe single crystal samples doped with palladium and nickel, with the purpose of determining whether the sintered samples can be used in different devices instead of single crystals. © 2009 Springer Science+Business Media, Inc.

AB  - 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.%, 0.7 at.% and 1.1 at.% Cr are presented and numerically analyzed. Local modes were determined at about 260 cm-1 and 480 cm-1 for PbTe doped with Cr and at slightly higher frequencies for PbSnTe doped with Cr. The origin of the local modes was discused about the possible application of the PbSnTe + Cr alloys. © 2009 Elsevier B.V. All rights reserved.

AB  - 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-1 and 285 cm-1) representing local B-impurity modes. The obtained results were compared with previously published data for a single crystal PbTe sample doped with boron.
