Half Heusler compounds are found to be promising candidates for many technological applications.
We present transport properties of several half Heusler compounds with wide range of band gap from 3 eV to 0.3 eV. The compounds show MgAgAs type cubic crystal structure (space group F4-3m).
LiZnAs and LiZnP show electrical resistivity of 10−1 Ωcm and 10−2 Ωcm at room temperature respectively. LiZnAs shows more than five order magnitude of electrical resistivity change in the temperature range from 100K to 150K.
