High‐Performance Pseudocubic Thermoelectric Materials from Non‐cubic Chalcopyrite Compounds

The pseudocubic approach is a new strategy to realize good electronic transport properties and a high thermoelectric figure of merit zT in non-cubic chalcopyrites through the utilization of cubic-like degenerate electronic bands, via the coexistence of a long-range cubic framework with short-range non-cubic lattice distortions.
