Possibility of n-type doping in CaAlSi-type Zintl phase compound CaZn ( = As, P)
Kazutaka Nishiguchi, Masayuki Ochi, Chul-Ho Lee +1
Motivated by a recent theoretical suggestion that doping electrons into various CaAlSi-type Zintl phase compounds may give rise to high thermoelectric performance, we explo…
Thermoelectric properties of (Ba,K)Cd2As2 crystallized in the CaAl2Si2-type structure
H. Kunioka, K. Kihou, H. Nishiate +4
As-Based Zintl compounds Ba1-xKxCd2As2 crystallized in the CaAl2Si2-type structure (space group P3-m1) were prepared using solid-state reactions followed by hot-pressing. We have s…
Electronic Origins of Large Thermoelectric Power Factor of LaOBiS2-xSex
Atsuhiro Nishida, Hirotaka Nishiate, Chul-Ho Lee +2
We examined the electrical transport properties of densified LaOBiS2-xSex, which constitutes a new family of thermoelectric materials. The power factor increased with increasing co…
High thermoelectric performance and low thermal conductivity of densified LaOBiSSe
Atsuhiro Nishida, Osuke Miura, Chul-Ho Lee +1
In this study, we examined the thermoelectric properties of the layered bismuth-chalcogenide-based (BiCh2-based) compound LaOBiSSe, which is expected to be a new candidate material…
Structural Phase Transition Accompanied by Metal - Insulator Transition in PrRu4P12
C. H. Lee, H. Matsuhata, A. Yamamoto +6
A structural phase transition has been found using electron diffraction technique in PrRu4P12 accompanied by a metal - insulator (M - I) transition (TMI = 60K). Weak superlattice s…
