n-Type skutterudites (R,Ba,Yb)yCo4Sb12 (R = Sr, La, Mm, DD, SrMm, SrDD) approaching ZT ≈ 2.0
Gerda Rogl,Gerda Rogl,A. Grytsiv,Peter Rogl,N. Peranio,E. Bauer,Michael J. Zehetbauer,Oliver Eibl +7 more
TL;DR: In this article, the influence of various fillers on the physical properties of triple and multifilled n-type skutterudites with the nominal composition (R 0.33 Ba 0.50 ) 0.35 Co 4 Sb 12.3 ) was investigated.
Journal ArticleDOI

TL;DR: In this article, a series of new data of hardness and elastic moduli (in some cases in dependence on composition, density and/or temperature), fracture resistance and thermal expansion, measured with various methods and equipments, as well as a comprehensive compilation of mechanical properties of p and n-type half-Heusler alloys is presented.
Journal ArticleDOI
Thermoelectric high ZT half-Heusler alloys Ti1−x−yZrxHfyNiSn (0 ≤ x ≤ 1; 0 ≤ y ≤ 1)
M. Gürth,M. Gürth,Gerda Rogl,Gerda Rogl,Vitaliy Romaka,A. Grytsiv,A. Grytsiv,E. Bauer,Peter Rogl +8 more
TL;DR: In this article, the binodal and spinodal curves in the isopleths of n-type TiNiSn and ZrNiSn were calculated in order to optimize heat treatment conditions.
Journal ArticleDOI
In-doped multifilled n-type skutterudites with ZT = 1.8
Gerda Rogl,Gerda Rogl,A. Grytsiv,A. Grytsiv,Kunio Yubuta,Stephan Puchegger,Ernst Bauer,Ch. Raju,Rc C. Mallik,Peter Rogl +9 more
TL;DR: In this article, the authors maximize the thermoelectric (TE) figure of merit, ZT, of n-type skutterudites via three different routes: (i) find the optimum fraction of In as fourth filler, (ii) check the influence of powder particle, grain, and crystallite size on the TE properties and (iii) check thermal stability.
Journal ArticleDOI
Skutterudites, a most promising group of thermoelectric materials
Gerda Rogl,Peter Rogl +1 more
TL;DR: In this paper, a review summarizes and discusses the latest research activities (after 2014) on p-and n-type skutterudite thermoelectrics, including the p-type and n type.
