Low-Temperature Transport Properties of In x Fe y Co4−y Sb12

Thermoelectric properties of In0.2Co4Sb12 skutterudites with embedded PbTe or ZnO nanoparticles

“…Noteworthy, neither the presence of PbTe nor the presence of ZnO influences the electron concentration in agreement with the thermopower data. The Hall mobility of the In 0.2 Co 4 Sb 12 sample is in agreement with literature data [47,50]. The presence of PbTe, ZnO and pores does not modify the scattering mechanisms of electrons i.e.…”

In-doped multifilled n-type skutterudites with ZT= 1.8

“…There are also attempts to improve the TE properties by doping and/or alloying e.g. substituting Co by Fe [33,[54][55][56][57][58], by Ni [31,59,60] and by Rh [61][62][63] or doping of the Sb site by Ge [20,64], by Se [65] and by Te [66][67][68][69]. Also double filled (Ba, In), substituted (Fe, Co) and doped (Sb by Ge) were investigated [36].…”
