Thermoelectric properties of Ti0.3Zr0.35Hf0.35Ni1.005Sn half-Heusler alloy

Journal of Applied Physics, 2019
Thermoelectrics enabling a direct conversion of waste heat into useful electricity is widely investigated for renewable energy applications. n-type half-Heusler (HH) MNiSn (M = Ti,Zr,Hf) thermoelectric (TE) elements are known as attractive semiconducting candidates for such purposes.

Electronic structure of half-Heusler semiconductor LiBeN

Physics Letters A, 2007
A new cubic half-Heusler structure LiBeN can be derived from the zinc-blende BN, and has a similar band structure to BN. The structural, elastic properties and band structures of LiBeN and zinc-blende BN were studied using the full potential augmented plane wave plus local orbitals method within density functional theory.

Topological Rare Earth Half-Heusler HoPtBi

2019
Magnetic HoPtBi is created and characterized as a new half-Heusler Weyl-candidate. By analogy with the well-studied GdPtBi system we undertake measurements intended to understand the normal state of this material, before extending our study to search for characteristics of Weyl behavior.

Mössbauer spectroscopic study of half-Heusler compounds

Hyperfine Interactions, 2006
The family of half-Heusler compounds offers a variety of half-metallic ferromagnetic materials. We have applied the Mossbauer spectroscopy to study the atomic order, local surroundings and hyperfine fields to several half-Heusler compounds. 121Sb Mossbauer study of the compound CoMnSb revealed the presence of two nonequivalent antimony positions in the

Theoretical search for magnetic half‐Heusler semiconductors

physica status solidi (b), 2003
AbstractElectronic structure and magnetic properties of half‐Heusler FeV1–xMnxSb, CoTi1–xMnxSb and RhZr1–xMnxSb for x ≤ 0.1 are studied from KKR‐CPA computations. Ordered compounds exhibit an energy gap at the Fermi level as large 0.45 eV (FeVSb), 0.95 eV (CoTiSb), and 1.14 eV (RhZrSb).
