CsPd0,875Cr0,125I3: перспективний кандидат для застосувань в області термоелектрики

We study the electronic structure, magnetization, and thermoelectric properties of CsPd0.875Cr0.125I3 obtained by doping CsPdI3 with atoms of the 3d transition metal Cr. By applying the generalized-gradient-approximation (GGA) and the GGA + U one, we found that CsPd0.875Cr0.125I3 alloy exhibits a co...

Zusammenfassung:We study the electronic structure, magnetization, and thermoelectric properties of CsPd0.875Cr0.125I3 obtained by doping CsPdI3 with atoms of the 3d transition metal Cr. By applying the generalized-gradient-approximation (GGA) and the GGA + U one, we found that CsPd0.875Cr0.125I3 alloy exhibits a completely metallic characteristic. Changes in the thermoelectric properties of the alloy are determined with the use of the BoltzTrap code. The electronic thermal conductivities (k/т), Seebeck coefficients (S), power factors (PF), and electrical conductivities (q/т) are calculated. The value of the ZT merit factor is near 1 at room temperature, by indicating that CsPd0.875Cr0.125I3 is a good candidate for thermoelectric applications at high and low temperatures.
