Journal of Magnetism and Magnetic Materials, 2020 Abstract The structural and magnetic properties of Bi doped CaMn7O12 (CMO) multiferroics are correlated with the results of electronic structures obtained from X-ray absorption spectroscopy. These compounds were prepared by using wet sol–gel technique and their X-ray diffraction patterns confirm the single phase formation.

Effect of Bi doping on thermoelectric properties of Ge0.90−xPb0.10BixTe compounds
Materials Science in Semiconductor Processing, 2020Abstract Doping is an effective way to optimize the performance of thermoelectric materials. In order to investigate the effect of Bi doping on microstructures and thermoelectric properties of Ge0.90Pb0.10Te, a series of Ge0.90−xPb0.10BixTe compounds were prepared by a melting-quenching-annealing process followed by spark plasma sintering.

Reducing Effective Mass for Advancing Thermoelectrics in Sb/Bi-Doped AgCrSe2 Compounds
ACS Applied Materials & Interfaces, 2020Liquid-like materials have attracted increasing attention, owing to their phonon-liquid electron-crystal feature. As a typical representative, the superionic conductor AgCrSe2 is regarded as a promising thermoelectric for its intrinsic ultralow lattice thermal conductivity.

Electrooxidation of some phenolic compounds at Bi-doped PbO2
Applied Catalysis B: Environmental, 2015It has been determined that bismuth content in the oxide grows from 0.49 to 1.81 wt% while increasing the Bi3+ ions additive concentration in the solution from 1 to 10 mM. It has been found that ionic additives affect the degree of hydroxylation of lead dioxide surface layer and the bond strength of the oxygen-containing particles.

Enhanced thermoelectric properties of Mg2Si0.58Sn0.42 compounds by Bi doping
Materials Letters, 2012Abstract N-type Mg2Si0.58Sn0.42 − xBix (0 ≤ x ≤ 0.015) compounds were prepared by melting the element metals in sealed tantalum tubes followed by hot pressing. The XRD results indicate that all samples are composites containing both major magnesium silicide solution phase and minor magnesium stannide solution phase.

Phase diagram and flux pinning in Bi-doping BaPbO3 compounds
Journal of Alloys and Compounds, 2018Abstract BaPb1−xBixO3-δ with x = 0.1–0.3 were prepared by a solid-state reaction method. X-ray diffraction patterns show that the cell parameters increase with the increasing x. From the result of transport measurement, we have drawn a BaPb1−xBixO3-δ phase diagram, which is divided into three regions: metal, semiconducting and superconducting. In the

Solid-state synthesis and thermoelectric properties of Bi-doped Mg2Si compounds
Current Applied Physics, 2011Abstract Bi-doped Mg2Si (Mg2Si:Bim, m = 0, 0.005, 0.01, 0.02, 0.03) was prepared by solid-state synthesis. The electronic transport properties (Hall coefficient, mobility and carrier concentration) and thermoelectric properties (Seebeck coefficient, electrical conductivity, thermal conductivity and figure-of-merit) were examined.
