Summary: In this study, we characterized the electrical and thermoelectric properties of layered WSe2 with thicknesses ranging from 10 to 96 nm at temperatures between 300 and 400 K. By electrostatically gating the devices with an ion gel, we were able to investigate both electron and hole behavior over a wide range of carrier densities. The highest n- and p-type Seebeck coefficients for thin-film WSe2 at room temperature, -500 and 950 μV/K respectively, were obtained in this study. We also highlighted the significance of low substrate thermal conductivity for lateral thermoelectric measurements, which improves the platform for future studies on other nanomaterials.

Summary: The investigation of the electrochemical reduction processes of Cu(II) and Se(IV) in solutions with poly(ethylene glycol) (PEG) provides important guidance for the preparation of Cu-Se alloy films with enhanced thermoelectric properties. PEG does not affect the reduction mechanisms but inhibits the reduction rates. The Cu-Se alloy film prepared under specific conditions exhibits strong thermoelectric properties.

Summary: In this study, the electrical resistivity, Seebeck coefficient, and power factor of an indium tin oxide (ITO) and nickel-chromium (NiCr) thermocouple were investigated. The thicknesses of ITO and NiCr were varied from 10 to 430 nm. The measured Seebeck coefficients were between 12.8 and (21.4 +/- 1.5) mu V K-1, respectively. The results showed that a reduction in thickness generally led to an increase in the Seebeck coefficient until a maximum value was reached. Among the measured samples, the optimal Seebeck coefficients were found with an ITO thickness of (111 +/- 4) nm and NiCr thickness of (18 +/- 2) nm. Finally, the power factor of the thermocouples was determined, with a maximum power factor of (84 +/- 7) mu W m(-1 )K(-2) for the ITO thickness of (111 +/- 4) nm and nickel-chromium thickness of (42 +/- 5) nm.

Summary: In this study, the effect of thermomechanical stress on the failure of multilayered thin films was investigated using analytical calculations and thermomechanical tests. The residual stress induced during material processing was calculated, and the weakest region of failure in the thin films was predicted. The test results confirmed that the film with maximum tensile residual stress is the most vulnerable to failure.

Summary: The high-temperature conductivity of perovskite oxides in LBCO thin films was studied by RF sputtering and thermal annealing. The conductivity varied depending on the substrate material and deposition process, with Co substitution for Cu resulting in increased conductivity and reduced temperature dependence. Transport properties were investigated to understand carrier generation mechanisms in LBCO films.

Summary: La0.8Sr0.2CrO3 (0.2LSCO) thin films were prepared using the RF sputtering method for thin-film thermocouples (TFTCs), with post-annealing processes optimizing properties for high-temperature sensing. XRD patterns showed pure phase with crystallinities increasing up to 1000 degrees C. The 0.2LSCO thin films exhibited improved stability and conductivity when annealed at 1000 degrees C, making them suitable for long-term monitoring of turbine engine temperatures.

Summary: This study successfully synthesized high quality ZnSe thin films using an economical and safer thermal evaporation method. By controlling the source to substrate distance (SSD) during the evaporation process, the crystal quality of the thin films was modulated. XRD scans confirmed the pure phase formation, while SEM analysis showed uniformity and smooth surface growth. The crystallite size increased from 28.73 to 40.18 nm with the increase in SSD. Raman analysis further confirmed the crystalline nature of the films. The transport properties, such as electrical conductivity, Seebeck coefficient, and power factor, varied with SSD. The highest values of Seebeck coefficient, electrical conductivity, and power factor (260 μV/C, 4.1 S/cm, and 2.21344 x 10-6 W/mK2 respectively) were achieved at an SSD of 10 cm.

Summary: There is growing interest in using antiferromagnetic materials for memory devices, with recent studies showing complications in interpreting resistive switching signals generated by high current densities in antiferromagnetic/heavy metal bilayers. Arpaci et al have introduced an experimental protocol to distinguish between magnetic and nonmagnetic switching signals in such structures, showcasing their method in IrMn3/Pt devices. The researchers utilized a six-terminal double-cross device to demonstrate reversible switching in the presence of IrMn3, effectively eliminating any non-magnetic switching artifacts.

Summary: A scaling law in the conductivity of 2D materials with tunable concentrations of ionized impurity scatterers is demonstrated. Experimental data collapses onto a single 2DCS curve when mobility is scaled by r and gate voltage is shifted by V-s. The analysis can be applied to various 2D materials systems with tunable impurity density, advancing materials characterization and improving sensor and transistor performance.
