Ultralow Lattice Thermal Conductivity and Colossal Thermoelectric Figure of Merit of the Room-Temperature Antiferromagnet CsMnBi
{{output}}
We study the experimentally synthesized layered material CsMnBi using first-principles calculations and the linearized electron and phonon Boltzmann transport equations. CsMnBi is found to be a semiconductor with an indirect bandgap of 0.76 eV and to realize C... ...
