DOI: 10.1002/aenm.202405024

Abstract: Ternary CaAl2Si2‐structure‐type Zintl compounds are promising p‐type counterparts to n‐type Mg3(Sb, Bi)2 for thermoelectric energy conversion. However, many of these p‐type Zintl compounds suffer from low carrier concentration and mobility, resulting in poor thermoelectric performance.… read more here.

recommendations! Published in 2017 at "Inorganic chemistry"

DOI: 10.1021/acs.inorgchem.6b01944

Abstract: Zintl phases form hydrides either by incorporating hydride anions (interstitial hydrides) or by covalent bonding of H to the polyanion (polyanionic hydrides), which yields a variety of different compositions and bonding situations. Hydrides (deuterides) of… read more here.
