Large thermoelectric power factor from crystal symmetry-protected non-bonding orbital in half-Heuslers

The intrinsic origin of high-power factors observed in half-Heusler alloys remains elusive, limiting the design of new thermoelectric materials. In this work, the authors reveal it is due to weakened electron–acoustic phonon coupling, originating from crystal symmetry protection of non-bonding orbit...
