GaC-family crystals, a new generation of star thermoelectric materials, achieved by band degeneracies, valley anisotropy, and strong phonon scattering among others

Using density functional theory combined with the Boltzmann transport equation, we uncover a new class of high-performance thermoelectric materials, i.e. , supertetrahedral Ga 4 C-family materials characterized by an ultrahigh thermoelectric figure of merit ( ZT ), which is produced both by a large...
