Large thermoelectric figure of merit for 3D topological Anderson insulators via line dislocation engineering

, 2010
We study the thermoelectric properties of three-dimensional topological Anderson insulators with line dislocations. We show that at high densities of dislocations the thermoelectric figure of merit ZT can be dominated by one-dimensional topologically ...

Thermoelectric performance of weakly coupled granular materials

, 2009
We study thermoelectric properties of inhomogeneous nanogranular materials for weak tunneling conductance between the grains, g_t < 1. We calculate the thermopower and figure of merit taking into account the shift of the chemical potential and the ...

AI‐Optimized Vanadium Oxide Multilayers for More Than 20‐fold Enhancement in Bolometric Performance

Advanced Science, EarlyView.
Machine‐learning‐optimized WxV1‐xOy multilayer thin films with graded doping achieve a high TCR (7.3 % K−1), reduced hysteresis, and low noise under CMOS‐compatible growth conditions. This approach overcomes the long‐standing trade‐off in microbolometers between linear response and performance, offering a universal bolometric parameter greatly enhanced

Manipulation of thermal conductivity and thermoelectric power factor via Hf-doping in FeNbSb half-Heusler alloys for enhanced thermoelectric figure of merit

Results in Physics
Bulk samples of FeNb1-xHfxSb (x = 0.0, 0.10, 0.20) alloys have been prepared by successive induction melting and mechanical alloying (MA). Electrical and thermoelectrical characteristics have been investigated as functions of temperature in the ...

Machine Learning Discovery of Record‐Low Lattice Thermal Conductivity in Double Perovskites

Advanced Science, EarlyView.
 A deep learning interatomic potential is introduced to predict forces for computing phonon properties and thermal transport behavior in double perovskites. Screening 9,709 compounds identifies 1,597 stable materials, and Boltzmann transport calculations including both three and four‐phonon scattering suggests a record‐low lattice thermal conductivity ...
