Symmetry-protected ideal Weyl semimetal in HgTe-class materials

, 2016
Ideal Weyl semimetals with all Weyl nodes exactly at the Fermi level and no coexisting trivial Fermi surfaces in the bulk, similar to graphene, could feature deep physics such as exotic transport phenomena induced by the chiral anomaly.

Synthesis and Thermoelectric Properties of Ni-Doped ZrCoSb Half-Heusler Compounds

Metals, 2018
The Ni-doped ZrCo1−xNixSb half-Heusler compounds were prepared by arc-melting and spark plasma sintering technology. X-ray diffraction analysis results showed that all samples were crystallized in a half-Heusler phase.
