Hierarchical Bonding Enables Dual-Channel Thermal Transport and Ultralow Lattice Thermal Conductivity in Zintl X2Te2 (X = Cs, Rb)

Zintl compounds are promising thermoelectric materials owing to their intrinsically low lattice thermal conductivity (κL), yet the microscopic origin of their thermal transport remains incompletely understood. Here, first-principles calculations combined with finite-temperature lattice dynamics, four-phonon scatterin...

Dimensionality Mismatch Enables Decoupled Heat and Charge Transport

Decoupling heat and charge transport is a key challenge in thermoelectrics. Here, we identify a route to spatially separate phonon and carrier transport in quasi-one-dimensional materials through high-throughput screening of the Materials Project database. Representative Sn$_2$S$_3$ and SbTeI exhibit a strong-intrachai...
