Аннотация: The ferroelectric properties of bismuth pyrostannate Bi2(Sn0.85Cr0.15)2O7 in the high-temperature region are established. The linear thermal expansion coefficient, electrical resistance, impedance, I−V characteristics, capacitance, loss-angle tangent, charge, and thermopower of the investigated material are measured in the temperature range of 300−700 K at frequencies of 102−106 Hz. Anomalies of the thermal expansion coefficient and hodograph spectrum variation in the region of polymorphic phase transitions are observed. The high resistance and change of the hopping conductivity for the tunnel-emission are found. The hysteresis in the electric field dependence of polarization is established. The change in the thermopower sign with temperature is revealed. The obtained experimental data are explained in the framework of the model of migration polarization by charged chromium ions.

Crystal structure and thermoelectric properties of mechanically activated LaCoO3 / V. A. Dudnikov, Yu. S. Orlov, L. A. Solovyov [et al.] // J. Taiwan Inst. Chem.

Rare-earth cobalt oxides -- Crystal structure -- Thermoelectric properties -- Mechanical activation
Аннотация: Background: Crystal structure of rare-earth LaCoO3 cobalt oxide subjected to high energy mechanical activation has been studied. In the temperature range of 300–800 K, the electrical conductivity and Seebeck coefficient were measured. Thermal conductivity was measured at 300–480 K. Methods: Comparative analysis of thermoelectric properties of the samples prepared by standard solid-state reaction and using high-energy mechanical activation was carried out. Findings: It was found that the experimental X-ray diffraction patterns are best described within the model that allows the coexistence of two domains in samples with the same crystal symmetry, but different lattice a and c parameters. The percentage ratio of these domains in the samples depends significantly on the size of the initial particles in the solid-state synthesis reaction and the annealing temperature. Mechanical activation and increase of synthesis temperature result in change of Seebeck coefficient sign and significant decrease of electrical resistivity. The Seebeck coefficient of non-activated samples takes positive values over the entire temperature range and decreases monotonically with increasing temperature, in contrast to mechanically activated samples exhibiting ambipolar behavior.

Transition metal trihalides -- Magnetic properties -- Thermoelectric -- conversion -- Density functional theory
Аннотация: Using DFT GGA calculations, electronic structure and magnetic properties of wide family of transition metal trihalides (TMHal3) (Zr, Ti and Nb iodides, Mo, Ru, Ti and Zr bromides and Ti or Zr chlorides) are investigated. These structures consist of transition metal atoms chains surrounded by halides atoms. Chains are connected to each other by weak interactions. All TMHal3 compounds were found to be conductive along chain axis except of MoBr3 which is indirect gap semiconductor. It was shown that NbI3 and MoBr3 have large magnetic moments on metal atoms (1.17 and 1.81 µB, respectively) but other TMHal3 materials have small or zero magnetic moments. For all structures ferromagnetic and anti-ferromagnetic phases have almost the same energies. The causes of these properties are debated.

Effect of A-site cation ordering on the thermoelectric properties of the complex cobalt oxides Gd1-xSrxCoO3-δ (x = 0.8 and 0.9) / V. A. Dudnikov [et al.] // Ceram.

Substituted rare earth cobalt oxides -- Thermoelectric oxide materials -- Ordered and disordered states
Аннотация: The effect of substitution of Sr2+ ions for Gd3+ ions on the phase composition, electrical resistivity, thermoelectricity, and thermal conductivity of rare-earth cobalt oxides Gd1-xSrxCoO3-δ (x = 0.8 and 0.9) has been investigated. It has been determined that at the investigated strontium concentrations, the single-phase disordered nonstoichiometric cubic perovskites and superstructures with ordered Sr2+/Gd3+ ions and anion vacancies can be formed. The influence of ordering/disordering of Gd and Sr cations over crystal-lattice A- sites on the thermoelectric figure of merit and sample stability at high temperatures has been studied. The thermoelectric figure of merit of the disordered samples was found to exceed by far the analogous parameter of the ordered samples, which allows us to consider the disordering as a way of improving the thermoelectric parameters. Two contributions to the conductivities are discussed: high-temperature thermoactivation and low-temperatures variable range hopping. The parameters of the Mott electronic structure, including DOS N(εF), hopping energy ε (the energy of hopping conductivity activation), and hopping length Rh, have been estimated.

Strontium titanate solid solutions -- Thermoelectric oxide materials -- Mechanochemical activation
Аннотация: The Sr1-xSmxTiO3 (х = 0.025, 0.05, 0.075, 0.1, 0.2) strontium titanate solid solutions were prepared from oxides and carbonates using a conventional ceramic technology based on the mechanochemical activation. The electrical conductivity and Seebeck coefficient of the synthesized compounds were measured in the temperature range from 300 to 800 K. We found that the properties of the samples significantly depend on the preliminary mechanochemical activation. The thermoelectric power factor attains maximum value in the hydrogen reduced samples with concentration of х = 0.05 and 0.075 obtained from nanoparticles: 5.5 μW/(cm · K2) for Sr0.95Sm0.05TiO3 (580 K) and 4.10 μW/(cm · K2) for Sr0.925Sm0.075TiO3 (650 K). An increase in the annealing temperature of mechanically activated samples leads to an even greater increase in electrical conductivity and power factor: 9.2 μW/(cm · K2) for Sr0.925Sm0.075TiO3 (650 K).

Effect of oxygen nonstoichiometry on electrical conductivity and thermopower of Gd0.2Sr0.8FeO3-δ ferrite samples / V. Dudnikov [et al.] // Materials. - 2019. - Vol. 12, Is. 1. - Ст. 74, DOI 10.3390/ma12010074. - Cited References: 24 . - ISSN 1996-1944

Rare-earth-substituted cobalt oxides -- Stability -- Thermoelectric properties
Аннотация: The behavior of the resistivity and thermopower of the Gd0.2Sr0.8FeO3−δ ferrite samples with a perovskite structure and the sample stability in an inert gas atmosphere in the temperature range of 300–800 K have been examined. It has been established that, in the investigated temperature range, the thermoelectric properties in the heating‒cooling mode are stabilized at δ ≥ 0.21. It is shown that the temperature dependencies of the resistivity obtained at different δ values obey the activation law up to the temperatures corresponding to the intense oxygen removal from a sample. The semiconductor‒semiconductor electronic transitions accompanied by a decrease in the activation energy have been observed with increasing temperature. It is demonstrated that the maximum thermoelectric power factor of 0.1 µW/(cm·K2) corresponds to a temperature of T = 800 K.

thermoelectric -- ferroelectric -- BaTiO3 -- Bi0.5Sb1.5Te3 -- coupling
Аннотация: An increasing number of studies have reported producing composite structures by combining thermoelectric and functional materials. However, combining energy filtering and ferroelectric polarization to enhance the dimensionless figure of merit thermoelectric ZT remains elusive. Here we report a composite that contains nanostructured BaTiO3 embedded in a Bi0.5Sb1.5Te3 matrix. We show that ferroelectric BaTiO3 particles are evenly composited with Bi0.5Sb1.5Te3 grains reducing the concentration of free charge carriers with increasing BaTiO3 content. Additionally, as a result of the energy-filtering effect and ferroelectric polarization, the Seebeck coefficient was improved by ∼10% with a ∼10% improvement in power factors. The BaTiO3 phase can effectively scatters phonons reducing lattice thermal conductivity κl (0.5 W m–1 K–1) and increasing ZT to 1.31 at 363 K in Bi0.5Sb1.5Te3 composites with 2 vol % BaTiO3 content giving an improvement of ∼25% over pure Bi0.5Sb1.5Te3. Our work indicates that the introduction of ferroelectric nanoparticles is an effective method for optimizing the ZT of Bi0.5Sb1.5Te3-based thermoelectric materials.

single-walled carbon nanotubes -- vacuum filtration -- thin films -- thermal conductivity
Аннотация: The single-walled carbon nanotube-based thin films with a thickness from 11 ± 3 to 157 ± 18 nm have been formed using vacuum filtration. The thermal conductivity of the thin films as a function of thickness and temperature up to 450 K has been studied by the 3ω technique. It has been found that, in the region of 49 nm, the supplied heat from a gold strip started propagating with the high efficiency to the thin film plane. The thermal conductivity of the thin films with a thickness of 49 ± 8 nm was measured using the 3ω technique for bulk samples. It has been found that the thermal conductivity of the single-walled carbon nanotube-based thin films strongly depends on their thickness and temperature. The thermal conductivity sharply (by a factor of ~60) increases with an increase in thickness from 11 ± 3 to 65 ± 4 nm. In addition, it has been observed that the thermal conductivity of the thin film with a thickness of 157 ± 18 nm rapidly decreases from 211 ± 11 to 27.5 ± 1.4 W m–1 K–1 at 300 and 450 K, respectively.

Composites -- BaTiO3 and titanates -- TiO2 -- Thermoelectric performance
Аннотация: The paper presents the results of preparing biphase SrTiO3–TiO2 ceramics as a promising system for n-type thermoelectrics using the features of a two-dimensional electron gas. Ceramics was obtained by reactive spark plasma sintering of SrCO3 and TiO2. The dynamics of phase transformations are shown; it is clarified that phase transformations are not the driving force of sintering. The mutual stabilization of the SrTiO3 and TiO2 phases is shown. Unique data on the assessment of the temperature gradient in the system have been obtained. A comparison of the thermoelectric characteristics of biphasic ceramics and its constituent phases allows concluding that the role of the two-dimensional electron gas is reduced to modulating the properties of bulk phases. Clear signs of size quantization were detected by the X-ray luminescence method, which is expressed in the blueshift of the luminescence spectrum by 22.3 ± 0.8 meV.

Аннотация: Ultra-wideband microwave filters with high frequency-selective properties have been developed by means of electrodynamic numerical analysis of 3D models. Microstrip structures, which are studied theoretically and experimentally, use one multimode resonator and a pair of single-mode resonators. There is fairly good agreement between the calculated data and the data taken on the experimental sample. The relative bandwidth of the manufactured microstrip filter is 60%.

Аннотация: The compound Bi24(CoBi)O40 has been synthesized using the solid-phase reaction method. The temperature and field dependences of the magnetic moment in the temperature range 4 K T 300 K and the temperature dependences of the EPR line width and g-factor at temperatures 80 K T 300 K have been investigated. The electrical resistivity and thermoelectric power have been measured in the temperature range 100 K T 1000 K. The activation energy has been determined and the crossover of the thermoelectric power from the phonon mechanism to the electron mechanism with variations in the temperature has been observed. The thermal expansion coefficient of the samples has been measured in the temperature range 300 K T 1000 K and the qualitative agreement with the temperature behavior of the electrical resistivity has been achieved. The electrical and structural properties of the compound have been explained in the framework of the model of the electronic-structure transition with inclusion of the exchange and Coulomb interactions between electrons and the electron-phonon interaction.

Аннотация: The structural, magnetic, electrical, and thermoelectric properties of GdXMn1-XS (0.01 <= X <= 0.3) solid solutions synthesized for the first time on the basis of alpha-MnS have been studied experimentally in the temperature range 77-1000 K in magnetic fields up to 10 kOe. The synthesized samples are antiferromagnetic semiconductors with an NaCl-type cubic lattice typical of a-MnS. Both concentration (X-c = 0.3) and temperature (T-c = 450 K) metal-insulator phase transitions have been observed. The concentration metal-insulator transition is accompanied by a decrease in resistivity and thermopower by twelve and two orders of magnitude, respectively, with the change in conductivity from p-type to n-type.
