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.

AB  - Single crystals of lead telluride doped with Nd were synthesized using the Bridgeman method. Room temperature far infrared reflectivity spectra were measured for PbTe samples with Nd content in the range 0.2-0.9 at.%. Optical reflectivity in the far infrared range was measured in the temperature range between 10 and 300 K for a highly polished PbTe sample with 0.6 at.% Nd. The experimental diagrams were numerically analyzed with a fitting procedure using a modified plasmon-phonon model. Two local modes were noted and their origin was discussed. Optical electron mobility was calculated for all analyzed samples.

AB  - 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 analyzed using first the Kramers-Kronig method and then a fitting procedure, based on the plasmon-phonon interaction model, and the optical parameters were calculated. Since the electronic structure of the ionized state for Pd, Ni and Pt is of the same type, and the influence of cl-shells is very strong, special attention was paid to the influence of the electronic structure of dopants on the final properties PbTe and PbSnTe crystals.

AB  - Far infrared reflectivity spectra of single crystal PbTe doped with Bi were measured and numerically analyzed using a fitting procedure based on a modified plasmon-phonon interaction model with two additional oscillators at about 140 and 219 cm(-1) which represents local Bi impurity modes. The position of observed plasma minimum and the values of the calculated parameters were compared with the literature data for pure single crystal PbTe which shows that bismuth improved the basic properties of the host crystal a lot.

AB  - 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 numerically analyzed using a fitting procedure based on the plasma-phonon interaction model and the optical parameters were determined, while two local modes of gadolinium were observed at about 155cm(-1) and 230cm(-1) at room temperature. The origin of these local vibrational impurity modes was discussed.

AB  - Thermal and electron transport properties of single crystal NiO were determined using the photoacoustic technique. NiO single crystals were prepared using the Verneuil method and were easily cleaved parallel to the (100) plane. All samples were of the p type. Atomic force microscopy images of cleaved NiO samples were made enabling a view of steps along the (001) direction and terraces, which were between 20 nm and 100 nm thick.
