Theoretical exploration of inherent electronic, structural, mechanical, thermoelectric, and thermophysical response of KRu4Z12 (Z = As12, Sb12) filled skutterudite materials

“…57–62 These properties include electrical conductivity ( σ / k ), electrical and thermal conductivity ( κ e ), Seebeck coefficient ( S ), and power factor (PF) under constant relaxation time approximations. The maximum conversion efficiency of the TE device is expressible as; 14 …”

“…Recent research has explored various TE materials, investigating their electrical and thermal properties. 14 The article titled "vibrational and structural properties of the RFe 4 Sb 12 (R = Na, K, Ca, Sr, Ba) lled skutterudites" discusses the vibrational and structural characteristics of lled skutterudites with different R elements (Na, K, Ca, Sr, Ba) through experimental and theoretical analysis. 15 "High spin polarization in the ferromagnetic lled skutterudites KFe 4 Sb 12 and NaFe 4 Sb 12 " explores the spin polarization properties of the ferromagnetic lled skutterudites KFe 4 Sb 12 and NaFe 4 Sb 12 , investigating their electronic structure and magnetic properties using experimental techniques and theoretical calculations.…”

Approaching the minimum lattice thermal conductivity in TiCoSb half-Heusler alloys by intensified point-defect phonon scattering

“…In addition to chalcogenides, 19,20 skutterudites, 21,22 silicides 23,24 and clathrates 25,26 extensively studied over the last decade for power generation applications, half-Heuslers (HH) alloys are promising candidates owing to their decent thermoelectric performance, low cost, composed via environmentally-friendly elements, good thermal stability and high mechanical robustness. 27–30 The cubic crystal structure of HH compounds with the XYZ stoichiometry is built up by four interpenetrated face-centered cubic (fcc) lattices with one vacant position.…”

“…6,7 Due to the independency of k L on electronic transport, limiting the propagation of heat-carrying acoustic phonons can be realized by various approaches 8 that notably include point-defect (atomic scale alloying) scattering, 9,10 bonding effect, 11,12 edge dislocations, 13,14 grain boundaries, 15,16 nano-sized grains, and the formation of in situ inclusion of nano precipitates in the host material. 17,18 In addition to chalcogenides, 19,20 skutterudites, 21,22 silicides 23,24 and clathrates 25,26 extensively studied over the last decade for power generation applications, half-Heuslers (HH) alloys are promising candidates owing to their decent thermoelectric performance, low cost, composed via environmentallyfriendly elements, good thermal stability and high mechanical robustness.
