Modulating phonon dynamics: tailoring lattice vibrations to enhance thermoelectric efficiency in Mg₃(Sb, Bi)₂ alloy

By modulating phonon dynamics via lattice softening and defect-induced strain in Mg₃Sb_1.5Bi_0.5, the authors achieve ultra-low thermal conductivity of 0.3 W m⁻¹ K⁻¹, and a ZT_max of 2.06, highlighting its potential for waste-heat recovery.

Self-optimized contact in air-robust thermoelectric junction towards long-lasting heat harvesting

The authors find a self-optimized contact resistivity in Sb/MgAgSb. After 100-day in air aging, the thermoelectric device can achieve 8.1% efficiency and 0.41 W/cm² power density, highlighting its potential for long-term heat harvesting.

Iterative sublattice amorphization facilitates exceptional processability in inorganic semiconductors

Sublattice amorphization is revealed as the deformation mechanism of Ag₂Te₁_–xS_x (0.3 ≤ x ≤ 0.6), based on which an iterative crystalline–amorphous transition strategy is proposed to enable these bulk inorganic semiconductors with metal-like processability.

Demonstration of valley anisotropy utilized to enhance the thermoelectric power factor

Valley anisotropy is proposed theoretically to benefit the electrical transport of thermoelectric materials but it lacks experimental demonstration. Here, the authors demonstrate how to utilize the single anisotropic Fermi pocket in p-type Mg₃Sb₂ to enhance its thermoelectric properties.
