Summary: Thermoelectric technology offers a promising solution to the global energy crisis by directly converting distributed heat into electricity. This study proposes a transfer learning strategy using a pre-trained neural network to accurately predict the ZT values of any thermoelectric material at any temperature. Compared to direct machine learning algorithms, the transfer learning model shows significantly improved predictive power, achieving higher Pearson correlation coefficients and lower mean absolute errors for both p-type and n-type systems.

Summary: Researchers investigated the electronic and thermoelectric transport properties of a new carbon-based material called schwarzite C-n using density functional theory and Boltzmann transport equation. They found that schwarzite has good conductivity and reactivity, and exhibits high thermoelectric performance in the low-temperature region. Among the studied schwarzites, C-8 achieved the highest thermoelectric figure of merit (T-z) of 4.91 at 255 K, while C-11 reached a maximum T-z value of 4.61 at 360 K. This study introduces a new carbon-based thermoelectric material with improved thermoelectric performance compared to existing carbon-based materials.

Summary: Density functional theory calculations were used to study the thermoelectric properties of phosphorene oxide (PO), revealing superior performance compared to pristine phosphorene. Spontaneous oxidation of phosphorene led to significant enhancement in thermoelectric properties of n-doped phosphorene oxide, attributed to reduced lattice thermal conductivity while maintaining electrical conductivity. These findings suggest that controlling oxidation could improve thermoelectric performance in nanostructures, with PO being a promising candidate for low-dimensional thermoelectric devices.
