Effect of Magnetic Moment on Carrier Effective Mass and Transport in Magnetic NdFeB Composite BiTe Films.

A composite of magnetic and thermoelectric (TE) materials is one of the most popular methods to improve TE properties. However, the influential mechanism of the magnetic property on the carrier has not been clarified. In this study, NdFeB cylinders are used as the magnetic phase to regulate carrier behaviors in BiTe films.

Thermoelectric Performance Enhancement of Film by Pulse Electric Field and Multi-Nanocomposite Strategy.

Thermoelectric (TE) film has wide potential application in low-grade waste heat recovery and TE generation due to its quick response and multifunctional integration. Multi-nanocomposite is a promising method to solve the difficulty of maintaining temperature difference and achieving a high figure of merit ZT. However, the depletion layer induced by the multi-nanocomposite typically degrades performance.

Effect of growth modes on electrical and thermal transport of thermoelectric ZnO:Al films.

Electrical and thermal transport controlled by growth mode can be used to optimize thermoelectric properties of ZnO:Al films, which was adjusted by the re-evaporation of Zn and Al via substrate temperatures. The growth modes include equiaxed crystal, columnar crystal and coexistence of both crystals. In the ZnO:Al film, equiaxed crystals improve the carrier mobility and reduce the lattice thermal conductivity.
