"large density-of-states effective masses and small conductivity effective masses... complex non-spherical iso energy Fermi surfaces in valence and conduction bands... low lattice thermal conductivity and electrical transport... excellent thermoelectric performances... localized nonmetallic dimers and rattling-like metal atoms on thermal transport... different carrier effective masses to electrical transport properties... could be used to predict and optimize the TE properties of other TE compounds"
