MM 16.4: Talk

Thermoelectricity in high-valley multiplicity materialsRoberta Farris1, Francesco Ricci2, Geoffroy Hautier2, Gian-Marco RIgnanese2, and •Vincenzo Fiorentini11Dip. di Fisica, Università di Cagliari, Italy — 2University of Louvain-la-Neuve, Belgium

We present a detailed theoretical study of two promising thermoelectrics, LaSO and YB4Mo, which turn out to have a large multiplicity and band complexity factor from a data mining search on a large electronic-structure database. Bands are computed ab initio and transport is studied in the Bloch-Boltzmann approximation; lattice thermal is modeled from the ab initio harmonic spectrum. The two materials reach a ZT of over 2 at typical temperatures.
